Head strips out easily

Julien Mott - 13th October 2019

These work fine unless you use loctite blue or above. They are low weight and high strength but a larger hex would improve these drastically. I have to use pliers to remove half of my bolts.

Hard to find screws

Gabriel - 29th October 2013

It is difficult to find such high-quality 4-40 button head screws with hex heads. I am using these in combat robot for strength and also on autonomous robot because they are low-profile and look cool!
