Value Collection 207491C Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION 207491C is a hex head cap screw designed for general fastening applications requiring corrosion resistance and mechanical strength. Sized at 1/2-13 x 1-1/2 inches with a unified national coarse (UNC) thread standard, this fastener is manufactured from 18-8 stainless steel for reliable performance in wet, chemical-exposed, or outdoor environments. The 3/4-inch hex drive accepts standard wrenches and sockets. It is used by plumbers, pipefitters, mechanical contractors, and industrial maintenance technicians who require a corrosion-resistant fastener in trade and light industrial settings.

This screw is suited for structural and mechanical assemblies where stainless steel is required to resist oxidation or chemical exposure. Common applications include pipe flange connections, HVAC equipment mounting, pump and compressor assemblies, and general mechanical fabrication. The 1/2-13 UNC thread is one of the most widely specified coarse-thread sizes in inch-standard fastener applications, making this screw compatible with a broad range of standard nuts, threaded inserts, and tapped holes found throughout trade work.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and chemically active environments
• 1/2-13 UNC thread standard ensures broad compatibility with inch-system hardware
• 1-1/2 inch length under head suits medium-depth fastening applications
• 3/4-inch hex drive accepts standard wrenches and impact sockets
• Inch measurement system for compatibility with standard trade tooling and hardware

Compatibility

Designed as an OEM-style replacement or direct-use fastener for any application requiring a 1/2-13 UNC hex head cap screw in 18-8 stainless steel. Compatible with standard 1/2-13 hex nuts, threaded flanges, and tapped components conforming to inch UNC thread specifications.

Installation Notes

Installation is performed by licensed tradespeople or qualified mechanical technicians using standard combination wrenches, socket sets, or impact drivers sized for a 3/4-inch hex drive. Ensure mating threads are clean and free of debris before installation. Do not mix stainless steel fasteners with dissimilar metals in environments prone to galvanic corrosion without appropriate isolation. Apply anti-seize compound when installing stainless fasteners into stainless tapped holes to prevent galling.
