Value Collection R63092229 Hex Head Cap Screw Brass

Product Description

The VALUE COLLECTION R63092229 is a brass hex head cap screw sized 1/2-13 x 2.5 inches, manufactured to Unified National Coarse (UNC) thread standards. This fastener is used in mechanical assemblies, plumbing fittings, and equipment mounting applications where corrosion resistance and non-sparking properties are required. The 1/2-13 thread designation indicates a 0.5-inch nominal diameter with 13 threads per inch. The length under head measures 2.5 inches. A 0.75-inch hex drive is standard for this fastener size, compatible with common wrenches and sockets. Brass construction makes this screw well suited for environments exposed to moisture, mild chemicals, or where galvanic compatibility with brass or copper components is needed.

This fastener is commonly installed in HVAC equipment panels, plumbing valve assemblies, pump housings, and general mechanical service applications. It is appropriate for use in both residential and light commercial settings where a corrosion-resistant, non-magnetic fastener is specified. Plumbers, HVAC technicians, and millwrights frequently use brass cap screws when joining brass or bronze fittings or when ferrous fasteners would cause galvanic corrosion issues. This screw is sold individually with a minimum order quantity of 2 pieces.

Key Features

• Brass construction provides corrosion resistance and galvanic compatibility with copper and bronze components
• 1/2-13 UNC thread conforms to Unified National Coarse inch-series standards
• 2.5-inch length under head suits medium-depth clamping and fastening applications
• 0.75-inch hex head drive accepts standard wrenches and sockets
• Non-sparking, non-magnetic material suitable for sensitive mechanical environments

Compatibility

Designed as a standard inch-series UNC hex head cap screw for use in any application requiring a 1/2-13 threaded brass fastener in plumbing, HVAC, or general mechanical assemblies.

Installation Notes

Install using a 0.75-inch open-end, box-end, or socket wrench. Ensure mating threads are clean and free of debris before installation. Do not overtighten brass fasteners, as the material is softer than steel and susceptible to thread stripping or shear under excessive torque. Shut off and depressurize any system before replacing fasteners in pressurized plumbing or HVAC assemblies.
