Value Collection 63609 Set Screw 1/2-13 X 1 in Cup Point Ss 316

Product Description

The VALUE COLLECTION 63609 is a 1/2-13 x 1 inch cup point set screw manufactured from Grade 316 stainless steel. It features a unified coarse (UNC) thread standard and is driven by a 1/4 inch hex key. The cup point tip bites into a shaft to resist rotation and axial movement without requiring a through-hole or external fastener head. Grade 316 stainless provides strong resistance to corrosion and chemical exposure, making it well suited for wet, marine, or chemically active environments. Machinists, millwrights, and maintenance technicians commonly install these in pulleys, collars, couplings, and shaft assemblies.

These set screws are used in light to medium-duty mechanical assemblies where a flush, headless fastener is required to lock a component onto a shaft. Typical applications include motor shaft couplings, shaft collars, gear hubs, and similar rotating equipment found in industrial, HVAC, and mechanical systems. The Grade 316 stainless construction makes them appropriate for food-service equipment, marine hardware, and other corrosive service environments. This listing includes a package of 25 screws, suitable for stocking or job-lot use.

Key Features

• Cup point tip digs into shaft surface for positive locking without surface damage typical of flat-point screws
• Grade 316 stainless steel resists corrosion, oxidation, and many chemical exposures
• 1/2-13 UNC thread for broad compatibility with standard tapped holes
• 1/4 inch hex drive accepts standard hex keys and Allen wrenches
• Headless design sits flush or below the surface for use in rotating or space-constrained assemblies
• Sold in a pack of 25 for stocking or multi-unit jobs

Compatibility

Designed as a direct-fit replacement or stocking fastener for any application requiring a 1/2-13 UNC cup point set screw with a 1/4 inch hex drive in Grade 316 stainless steel.

Installation Notes

Installation is performed by machinists, millwrights, or qualified maintenance technicians using a properly sized 1/4 inch hex key or Allen wrench. Always de-energize and lock out rotating equipment before servicing shaft assemblies. Ensure the tapped hole is clean and free of debris before threading the screw in. Do not overtighten, as excessive torque can strip the hex socket or distort the cup point tip.
