Socket Screw Fasteners

Socket screws, also referred to as set screws or grub screws, are threaded fasteners with a recessed drive, often called a hex socket or hexagon socket. These high-quality threaded fasteners are installed by using a hexagon-shaped key and can be tightened to higher torque specifications than a crossed recessed or slotted drive fastener.

Metric & Multistandard is your premier wholesale distributor of set screws along with many other metric fasteners or industrial components. We have built our business through our immediate product availability, outstanding customer service, and superior technical knowledge and support to find you the set screw or other fastener required for your application.
