1/2UNC Imperial Grub Screws

Description

Grub Screw – 1/2 UNC Stainless Steel
Our 1/2" UNC Grub Screws (also known as socket set screws) are designed for high-strength, low-profile fastening in mechanical assemblies where space is limited and a flush finish is essential. These headless fasteners sit completely within the tapped hole, providing secure internal clamping without any external protrusion.

The Unified National Coarse (UNC) thread offers strong engagement and excellent resistance to stripping, particularly in softer materials. Ideal for locking pulleys, collars, gears, and other components onto shafts, the 1/2" size makes these suitable for heavy-duty applications across industrial, automotive, and machinery sectors.

Equipped with a hex socket drive, they install easily with an Allen key, delivering precise torque and reliable performance under vibration or repeated use. Crafted from corrosion-resistant stainless steel, these grub screws are well-suited for both indoor and outdoor environments, including those exposed to moisture, chemicals, or mechanical wear.

Whether used in maintenance, assembly, or fabrication, our 1/2 UNC Grub Screws provide a clean, secure fastening solution built to last.
