M3 Metric Allen Socket Button Head Bolt, Black Stainless Steel
Button head cap screws are great for limited space installation areas. Use an allen wrench to install these screws.

These bolts can be used with many different styles of locking and non-locking nuts, tightly clamping together whatever the cap screw is being used to secure.
