3/8UNC Imperial Grub Screws
Description
Grub Screw – 3/8 UNC Stainless Steel
Our 3/8" UNC Grub Screws (socket set screws) are heavy-duty, headless fasteners designed to provide secure internal clamping in mechanical assemblies without protruding above the surface. Perfect for locking components like pulleys, collars, and gears onto shafts, these screws are ideal for use in applications where a flush, clean finish is essential.
The 3/8" UNC (Unified National Coarse) thread offers strong grip and fast installation, making it suitable for industrial and machinery applications where ease of assembly and resistance to loosening are critical. The coarse thread profile performs especially well in tapped holes in softer materials.
Fitted with a hex socket drive, these screws are easily installed using an Allen key, offering precise torque control and reduced risk of slippage or stripping. Made from corrosion-resistant stainless steel, they’re built to perform in tough environments including outdoor, damp, or chemical-exposed settings.
Whether used in fabrication, repair, or assembly, our 3/8 UNC Grub Screws provide a strong, low-profile fastening solution engineered for long-lasting performance.
