Review on 🔩 Threaded Stainless Fasteners with Knurled Finish Screws by Tim Larsen

This screw was advertised as a #4-40 screw. I have a mechanism that needed a replacement set screw. It is listed in size 4-40 and I always buy that size. I thought it would be a good replacement and can be used without a screwdriver. I bought and didn't test for the first 30 days. I have noticed that this product is NOT returnable after the first 30 days. Today is day 37 and I've tried and the screw won't even catch the threads. It definitely didn't fit. DO NOT TRUST THE FEATURES OF THIS PRODUCT.
