Value Collection 208777C Hex Cap Screw 1/2-13 X 2-1/4 in 18-8 Ss

Product Description

The VALUE COLLECTION 208777C is a hex head cap screw machined to inch-system dimensions and suited for general mechanical and structural fastening applications. It carries a 1/2-13 UNC thread size and measures 2-1/4 inches under the head. Constructed from 18-8 stainless steel with a bright, uncoated finish, it offers reliable corrosion resistance in wet, outdoor, and mildly corrosive environments. The partial threading on the shank allows for clamping without thread engagement along the full grip length, which is useful in applications requiring a defined bearing surface. Installers across HVAC, plumbing, electrical, and mechanical trades reach for this fastener for equipment mounting, panel attachment, and component assembly work.

This screw is appropriate for use in both residential and light commercial service environments where stainless steel fasteners are specified. Typical applications include equipment mounting frames, access panel hardware, pipe support assemblies, and general mechanical enclosures. The UNC thread form mates with standard inch-system tapped holes and nuts. The 1/2-13 thread pitch is one of the most common coarse-thread sizes found in trade equipment, making this a straightforward drop-in fastener for maintenance and repair scenarios.

Key Features

• 1/2-13 UNC coarse thread for compatibility with standard inch-system tapped holes and hardware
• 2-1/4 inch length under head suits medium-depth fastening applications
• 18-8 stainless steel construction provides corrosion resistance without a coating
• Partially threaded shank enables positive clamping at the grip zone
• Bright, uncoated finish — no risk of coating interference with electrical or sensitive mating surfaces
• Hex drive head works with standard wrenches and sockets common on any service truck

Compatibility

Designed as a standard inch-series hex head cap screw for use anywhere a 1/2-13 UNC partially threaded fastener in 18-8 stainless steel is specified.

Installation Notes

Installation is performed with a standard open-end, box-end, or socket wrench sized for a 1/2-inch hex cap screw. Power down and de-energize any electrical equipment before fastening or removing hardware in proximity to live components. Ensure the mating threaded hole or nut is clean and free of debris before driving the fastener. Do not exceed the torque rating of the mating component or tapped material, and avoid mixing with dissimilar metals in environments prone to galvanic corrosion.
