Value Collection 208813 Hex Head Cap Screw 1/2-13 X 5.5 in

Product Description

The VALUE COLLECTION 208813 is a hex head cap screw designed for general mechanical fastening applications across trade, industrial, and construction environments. Sized at 1/2-13 thread and 5-1/2 inches in length under head, this fastener is partially threaded and manufactured from 18-8 stainless steel with a bright, uncoated finish. The 18-8 grade provides solid corrosion resistance, making it a reliable choice where moisture or mild chemical exposure is a concern. Plumbers, HVAC technicians, electricians, and general tradespeople commonly use this size for equipment mounting, structural connections, and mechanical assemblies. The UNC thread standard ensures broad compatibility with standard inch-system nuts and tapped holes.

This screw is suited for light industrial and commercial applications requiring a corrosion-resistant fastener in an inch-series size. The partially threaded shank provides a smooth bearing surface through the grip zone, which is useful in bolted joint assemblies where shear load distribution matters. It is sold in a minimum order quantity of 5 pieces, with a package quantity of 1 per unit. Typical install scenarios include equipment framing, mechanical supports, pump and motor mounting, and panel or enclosure attachment.

Key Features

• 1/2-13 UNC thread for compatibility with standard inch-system fastener hardware
• 5-1/2 inch length under head for deep grip or through-bolt applications
• 18-8 stainless steel construction provides corrosion resistance in wet or mildly corrosive environments
• Partially threaded shank allows load distribution through the unthreaded grip zone
• Bright uncoated finish — no plating to crack, chip, or introduce galvanic risk with stainless mating hardware
• Minimum order quantity of 5 units ensures practical stock quantities for field and shop use

Compatibility

Designed as a standard inch-series hex head cap screw compatible with 1/2-13 UNC threaded nuts, inserts, and tapped holes in steel, aluminum, and other structural materials per standard inch fastener specifications.

Installation Notes

Install using a standard 3/4-inch hex wrench, socket, or impact driver with an appropriate hex socket. Ensure mating threads and tapped holes are clean and free of debris before installation. Follow applicable torque guidelines for 1/2-13 stainless fasteners from a recognized fastener standard such as ASME B18.2.1. Avoid overtorquing stainless steel fasteners, as 18-8 alloys are susceptible to galling — apply an anti-seize compound to threads when working in high-friction or elevated-temperature conditions.
