How to Use MF Supply’s Cross-Reference Tables to Find Equivalent Fasteners Faster

Many popular fastener brands, from Keensert® key-locking inserts to precision shoulder screws, have alternative form-fit-function equivalents available in Mil-Spec, commercial or generic versions. The fastest way to identify the right alternative without guessing is by using cross-reference tables

At MF Supply, we’ve built and curated multiple product-specific cross-reference tables so buyers can confidently match OEM brands, Mil-Spec part numbers, and generic equivalents, saving time, money, and lead time risk, while maintaining quality and compliance. 

Below is your quick-start playbook. 

We currently publish, maintain, or reference cross-reference data for high-demand categories. On our website, the Inch, Mil-Spec & Metric Fasteners Cross-Reference Charts category serves as your central hub. Once there, you can drill down into specific product families:  

Each product family/category links to cross-reference charts that map: 

  • OEM brand part numbers/products 
  • Mil-Spec (MS, NAS, MA, NA) series (if applicable) 
  • Generic functional equivalents 
  • Sizes, materials and other specifications 

Popular product categories include adhesives and sealants, anchors, bits and nutsetters, cage nuts, flex type lock nuts, handles, Keenserts®, knurled thumb screws, nylon insert stop nuts,  precision shoulder screws, retaining rings, rivets & blind threaded inserts, self-clinching, fasteners, spacers and standoffs, speed clips, spring nuts, weld nuts, weld studs, and woodworking screws. 

3 STAR RIVETS USA, ABBATRON®, ALCOA, AMATOM®, APEX®, ARCONIC®, ATLAS®, AVDEL®, AVK®, B. F. GOODRICH, BOLLHOFF, BUCKEYE, CAPTIVE, CELUS®, CHERRY®, CONCORD, EZ-Lok, FASTENAL, GESIPA®, GRIPCO®, GLOBE ELECTRONICS, GRAINGER, H. H.

When you’re chasing cost savings, cutting lead time, or finding a compliant alternative, our cross-reference charts make it fast and fail-proof. Here’s the playbook:

  1. Visit our Cross-Reference Hub
    Head to the Inch, Mil-Spec & Metric Fastener Cross-Reference Charts on mfsupply.com.
  2. Select Your Product Category
    Pick the family you’re working with (Keenserts®, shoulder screws, dowel pins, etc.).
  3. Locate Your Identifier
    Find the OEM brand part number or Mil-Spec/NAS/MA/NA code inside the chart.
  4. Match the Technical Requirements
    Click through to the referenced item and verify the functional equivalency: material, plating/finish, thread/diameter, length, fit/series, and any spec callouts.
  5. Order or Request a Quote With Requirements
    Purchase online or submit an RFQ — and let us know if you need COC, MTR, DFARS, REACH/RoHS, Country of Origin, or other compliance docs.

Fastener buyers often ask: How can I determine if I must use the brand name or if I can cross to a generic part?  

Use this handy 4 point checklist as your guide: 

  • Does your bill of materials specifically call for the OEM brand-name fastener or component? 
  • Can you live with the lead time or will having parts sooner improve delivery of the final product? 
  • Will your supplier provide a certificate of conformance? 
  • Will saving money help you be more competitive? 

Do not cross when: 

  • The BOM mandates the OEM brand, and the end customer may not be flexible
  • Traceability or contract terms prohibit substitution 
Product TypeResultSavingsLead-Time Impact
Precision Shoulder ScrewCrossed to 8 valid equivalentsMajor cost reductionImmediate availability

If you’re unsure, send us the part number, drawing, photo, or BOM section. We’ll match it, validate compliance, and offer your best-value, best-availability option.

A286 Stainless Steel Keenserts®: Stronger Threads for High-Temperature & Corrosive Applications

If your next thread reinforcement or repair project involves corrosive, high-load, or high-temperature conditions, A286 stainless steel Keenserts® (key-locking inserts) may be your best choice.

In this guide, you’ll learn:

  • What A286 Superalloy is
  • Key benefits of using A286 Keenserts®
  • How to identify A286 in part numbers
  • Available series and styles
  • Industries and applications that rely on A286 Keenserts®

What Is A286?

A286 is an iron–nickel–chromium stainless steel superalloy known for:

  • High strength (maintains properties at up to 1300°F / 700°C)
  • Excellent corrosion & oxidation resistance
  • Performance in both extreme heat and low-temperature environments

It is widely used in gas turbines, aerospace components, and assemblies that face frequent exposure to extreme conditions. This alloy can also be age-hardened to improve ductility in notched sections.

Why Choose A286 Keenserts®?

Keenserts® are solid, one-piece threaded inserts designed for permanent, high-strength threads—especially in softer materials or under intense heat and torque.

Here’s why A286 stainless steel Keenserts® stand out:

1 – High-Temperature Strength

A286 retains its strength where others fail—ideal for exhaust zones, turbines, and engine bays. Its oxidation resistance and heat-treat response ensure long-lasting performance.

2 – Mechanical Locking Keys

Drive keys lock the insert into the parent material, resisting torque-out and rotation even in vibration-heavy assemblies. This ensures reusable, secure threads during multiple maintenance cycles.

3 – Aerospace-Grade Quality

With minimum tensile strength of 140 ksi, finishes meeting AMS 2700 / ASTM B700, and 302 CRES keys, these inserts meet stringent military and aerospace specs.

4 – Simple Installation

Uses standard drills and taps—no STI tap required. Just tap the hole, insert, and drive in the keys. For parent materials harder than RC30, a broaching tool is recommended to cut key slots.

Note: A286 can be costlier and harder to machine, with potential long lead times.

How to Identify A286 in Part Numbers

Look for these designators:

  • Mil-Spec: CA (e.g., MS51831CA204, NAS1395CA6)
  • Commercial: JT (e.g., KNH624JT)
  • Metric Commercial: T (e.g. KNCM4x0.7T)
  • Metric Mil-Spec: NA Series NA0147, NA0149, & NA0151

Example:

Why Use Nitronic Keenserts vs. Nitronic Helicoils?

Nitronic Keenserts Key-Locking Inserts Available at MF Supply

If you need Nitronic material for your thread repair or thread reinforcement project, you might be deciding between helical and/or key-locking inserts. Here are some considerations to help you evaluate which product will best solve for your needs.

But first, let’s take a closer look at Nitronic 60…

What Makes Nitronic Special?

Nitronic 60, the most commonly used Nitronic material used to manufacture inserts, is a high-performance stainless steel alloy enriched with nitrogen, renowned for its exceptional wear, galling, and corrosion resistance. It provides exceptional resistance to crevice corrosion, general corrosion and high temperature oxidation, This makes it ideal for applications that require durable and reliable thread repair or reinforcement in marine environments, chemical processing equipment, and assemblies that require frequent disassembly.

Nitronic Keenserts® vs. Helicoils

Helicoils (helical inserts) are used for thread repair and reinforcement. They are considered the simplest way to repair stripped or damaged threads. Helical wire inserts are the way to go when reducing costs and minimizing space are priorities. Helicals are useful for creating permanent strong threads in softer materials, in lower heat and lower torque environments, or to convert threads between inch and metric sizes.

So what’s the the catch?

Helicals have certain limitations that Keenserts® (key-locking inserts) overcome. Keenserts are the best bet in heavy wear, high vibration and high heat situations where saving space is not a concern and the hole depth is limited.

If your project calls for Nitronic inserts, below are four reasons why you should consider choosing Keensert® style key-locking inserts vs. Nitronic helical inserts:

  1. Superior Strength and Stability: Nitronic key-locking inserts have locking keys that mechanically lock the insert into place, offering superior resistance to vibration and torque-out compared to helical inserts, which rely solely on friction.
  2. Enhanced Durability: The durable design of key-locking inserts provides greater resistance against thread stripping and wear, making them suitable for repeated assembly and disassembly without compromising the integrity of the threads.
  3. Corrosion and Galling Resistance: Both helical inserts and key-locking inserts made from Nitronic 60 offer excellent corrosion resistance. However, key-locking inserts provide additional structural integrity, especially crucial in harsh environments where component failure is not an option.
  4. Easier Installation and Maintenance: Nitronic key-locking inserts require no special taps or tools for installation beyond standard equipment—a pneumatic power tool is recommended if installing key-locking inserts in the thousands—reducing downtime during maintenance or initial assembly. Their solid, one-piece design simplifies handling and reduces the likelihood of installation errors.

Unsure which Nitronic 60 insert is ideal for your next thread-repair or reinforcement project? Send us your questions, we’re here to help!
