Grub Screw

Grub Screws, also known as Set Screws, are headless fasteners designed to secure one component inside another without protrusion. They are tightened with an Allen key through the internal hex socket, leaving a flush or hidden finish. Available in various point types, they provide grip, locking, or positioning in mechanical assemblies. Manufactured to ASTM and DIN standards, they are offered in multiple grades, materials, and coatings. They are widely used in machinery, pulleys, gears, couplings, and precision engineering applications.
