Button Socket Cap Screw: 5/16-18, 1/2" Length Under Head, Stainless Steel, Bright/Uncoated MPN:3TSBS95C008

The 5/16-18 x 1/2 inch under head hex socket drive button socket cap screw is designed to withstand demanding applications requiring high torque resistance and vibration fatigue endurance while providing stability, shear strength and equal loading. It features a black oxide finish for corrosion protection, making it ideal for outdoor installations. The button head design provides clearance with its low-profile cap that distributes stress evenly around the caphead, preventing cracking or rounding off under high-tensile force. Its stainless steel composition offers superior durability and corrosion resistance. Its applications include automotive and aerospace door hinges, hoods, trunks, deck lids, construction and industrial projects with a need for maximum tightening torque.
