4-40 X 1/4 FLANGE BUTTON SOCKET CAP SCREW ALLOY BLACK
Description
The radius on the Flange Button Head presents a streamlined profile, virtually eliminating the sharp edges which could occur with a bolt and washer assembly. As the large under-head surface pressure by area is low, they can also be used with softer materials without harm or damage.
Applications/ Advantages
Flange facilitates greater load spread and streamlined appearance; Deep, accurate socket for maximum key engagement, and precision-forged head for continuous grain flow and maximum strength.
