Personal Protective Equipment under the EUA and Appendix A

What is the FDA Authorized Appendix A list under the EUA, and why is it important?

What is the EUA?

The EUA or Emergency Use Authorization is evoked during public health emergencies like COVID-19. Through this authorization, the Food and Drug Administration tries to make sure that the public and the medical field have enough medical devices to manage the crisis. They do this by allowing unapproved medical products or medical products that are approved for one use to be used in a different setting to prevent shortages.

Surgical Masks and Non-NIOSH Respirators Under Appendix A

Appendix A PPE

There are two products in Appendix A: surgical masks and non-NIOSH respirators that are made in China.

This is important because you want to know that the mask you are wearing is effective- especially in a pandemic.

So, the FDA has tested and continues to test certain categories of masks to get them on Appendix A to say they are approved for use in a medical setting.

How Do Products Get Put on the EUA?

Companies who want their product to be listed and certified under the EUA can apply for their products to be tested. There is a specific testing protocol that the FDA, in collaboration with the CDC, uses in order to approve products.

Is Your KN95 Mask or other PPE Listed Under the EUA?

Keensert Installation Tool Kits

Keensert Installation Tool Kits

Keenserts are very small but very strong key locking inserts used across many industries, especially in aerospace and precision manufacturing. While Keenserts are easy to install, it is essential to have all of the necessary tools to properly install them.

What Hole Size and Tools do I Need to Install My Keenserts Manually?

This is a common question we receive from manufacturers, so today, we are going to share everything you need to know to install your key locking inserts.

Prior to installing a key locking insert, you have to check with the supplier to make sure you have the proper drill and tap. Each part number has its own combination of drill and tap. This is really important, and it’s based on the outside and inside diameter.

Check out our Keensert Buyer’s Guide, Keensert Cross-Reference Guides, and How to Manually Install Keenserts.

Commercial or Military Key Locking Inserts?

It’s also important to note that each key locking insert has different types of thread depending upon their military or commercial. So, prior to installing the inserts, you need to have the following information…

  • Nose assembly.
  • Drill and tap size for the insert you’re installing.
  • The fastener you’re installing.

Tools For Keensert Installation:

  • Drill
  • Drill Bit
  • Drill or Tap Wrench
  • Tap
  • Countersink Tool
  • Keensert Installation Tool
  • Hammer

What is a Broaching Tool, and When Will I Need One?

A broaching tool is an extra installation tool that is used for very hard parent materials such as A286 or A4140. The purpose of the broach is to create slots for the keys in the parent material when the regular tools won’t cut it.

Installing Key Locking Inserts with Pneumatic Power Tools

In last week’s blog, we discussed when and how to install key locking inserts manually. If you have a few hundred inserts to install, the manual process is fine. However, if you are installing these Keenserts by the thousands, then you will want to use a pneumatic power tool to speed up the processes.

How to Install Keenserts with a Pneumatic Tool

  • The beginning of the installation process is the same as a manual installation.
  • Drill and Countersink the Material
  • Tap the Material
  • Manually Insert the Key Locking Insert
  • The next step is to use the power tool to simply screw the key into place.

You can see how this process can save you so much valuable time if you are installing the key locking inserts by the thousands!

How to Manually Install Key Locking Inserts

What is a Keensert?

A Keensert or key locking insert is a solid bushing style insert that is threaded on both the inside and the outside and has wedges or “keys” attached at the top. These inserts are used to distribute loads and repair or strengthen threads against failures due to stripping, seizing or corrosion. They are commonly used in precision manufacturing and aerospace applications.

Check out our Buyer’s Guide to Keenserts!

What is the Best Way to Install Keenserts?

There are a few methods used to install key locking inserts. Manual installation is best for assemblies that are in the hundreds, but if you are installing a lot of Keenserts, pneumatic installation is the way to go.

Keensert Manual Installation

  1. Drill and Countersink the Material
  2. Tap the Material
  3. Manually Insert the Key Locking Insert
  4. Use the Installation Tool to Drive the Keensert

Buyers Guide to N95 Face Masks

At MF Supply, we carry all of the personal protective equipment you need to keep your business safe. In today’s blog, we are discussing the different styles of N95 masks we have available.

N95 Face Mask Styles

Cup Style Face Mask

The first and most popular style of N95 masks is the cup style. This is the 3M style that everyone wants to get their hands on. There are several different versions of the cup style masks here at MF Supply: 3M 8210 and the Guangzhou Harley L288. We also carry the Makrite N95-9500 which is a Surgical Respirator with 510k certification.

Both of these cup style masks offer a close fit with head straps and nose pieces.

Folding Style Face Mask

The Guangzhou Harley L188 folding face mask is another popular style of protective respirator mask that is great for on the go. Since they fold up so neatly, it is easy to store it in your pocket or in a bag if you are going in and out of environments where an N95 is required.

This style also has 2 head straps and a nose piece for a close fit.

Pouch Style Face Masks

The duckbill or Pouch style N95 is a less widely known style of respirator mask, but it offers a large breathing pouch for easier breathing while wearing. IN this video we whocase the Kimberly Clark Kimtech 53358 N95, which is made in the USA.


Do N95 Face Masks Come in Different Sizes?

Some manufacturers do offer different size N95 masks from small to extra large.

N95 Face Mask Certifications

All of the N95s we offer come with OSHA certifications through NIOSH. The difference between the standard N95s in this blog and FDA 510K surgical N95 respirators is that surgical respirators come with an additional 510K certification from the FDA, and those are meant to be used in surgery or a medical environment due to their splash resistant rating. However, all the N95 masks that we discussed today have also been blanket certified for medical use under the FDA’s Emergency Use Authorization during Covid-19.

N95 Face Masks Fit Testing

All in N95 masks require fit testing by each wear, which happens every year. Learn More!

N95 Mask Comparison Guide

Check out this useful N95 respirator comparison guide for clarification on some of the main differences in N95 styles and uses.

Hardware Functional Equivalents and Sourcing Experts

At MF Supply, we spent a lot of time sourcing hard to find, back ordered, expensive, or out-of-stock OEM hardware brands. We do this in order to save money and to reduce long lead times for our customers.

Just like in the pharmaceutical world, where there are brand names that everyone knows, there are also generic brands that are functional equivalents. This is true for the hardware industry too!

What is a Functional Equivalent?

Some brand-name fasteners are also available as functional equivalents, also referred to as crossed, generics, or alternatives. These are parts that are the same in form, fit, function, material, and specifications as the brand name.

Functional Equivalents Examples and Case Studies

Below are two case studies showing how using functional equivalents has saved a lot of manufacturers a lot of money and time.

Case Study: Precision Shoulder Screw Functional Equivalent

In this case study, you can learn more about precision shoulder screw functional equivalents.

Case Study: Keensert Functional Equivalents

In this case study, you can see that smart manufacturers use brand equivalents to save time and money!

Should You Use Functional Equivalents?

On our website, we offer some of our different product reference charts that actually show you the different part numbers that all our functional equivalents.

Four Point Check Checklist

  • Check your BOM- Does it call for an OEM brand?
  • Are the Lead Times going to hinder your timeline? Will having the part sooner improve the delivery of your final product.
  • Will your supplier provide you with the certificate of conformance to certify that the part is a functional equivalent to the original brand you are looking for?
  • Will saving money help you be more competitive in your market?
