Value Collection VS1176PR Hex Head Cap Screw 1/2-13 X 2-1/2 in

Product Description

The VALUE COLLECTION VS1176PR is a fully threaded hex head cap screw designed for fastening applications that require corrosion resistance in wet, marine, or chemically exposed environments. Manufactured from silicon bronze alloy C651, this fastener measures 1/2-13 thread size with a 2-1/2 inch length under head and a 3/4 inch hex drive. It meets ASME B18.2.1 standards and carries a bright, uncoated finish. Licensed plumbers, marine contractors, and industrial maintenance technicians commonly specify silicon bronze hardware where stainless or carbon steel fasteners are unsuitable due to galvanic compatibility or salt exposure concerns.

This cap screw is suited for residential and commercial plumbing, marine deck hardware, electrical enclosures, and general mechanical assemblies where corrosion-resistant fasteners are required. The UNC thread standard makes it compatible with standard inch-system tapped holes and nuts. Its fully threaded shank allows consistent clamping across varying material thicknesses. Applications include pipe flange connections, pump mounting, and fixture installations in corrosive or high-humidity environments.

Key Features

• Silicon bronze alloy C651 construction for superior corrosion resistance in marine and wet environments
• Fully threaded shank provides consistent engagement along the entire fastener length
• Meets ASME B18.2.1 dimensional standards for hex head cap screws
• UNC thread standard ensures compatibility with standard inch-system hardware
• Bright, uncoated finish with no additional plating that could compromise galvanic compatibility
• 3/4 inch hex drive accepts standard wrenches and sockets

Compatibility

Designed as a standard inch-system hex head cap screw with 1/2-13 UNC threading, compatible with matching UNC nuts, threaded inserts, and tapped holes conforming to ASME B18.2.1 specifications.

Installation Notes

Installation is performed using a standard 3/4 inch open-end, box, or socket wrench. Ensure the mating tapped hole or nut is clean and free of debris before threading to avoid galling, which silicon bronze alloys can be susceptible to under high torque. Applying an appropriate anti-seize compound is advisable in high-humidity or submerged installations. Always follow applicable mechanical and plumbing codes for fastener selection and joint assembly.
