Value Collection 30731 Hex Head Cap Screw 1/4-20 X 3/4 in

Product Description

The VALUE COLLECTION 30731 is a silicon bronze hex head cap screw with a 1/4-20 thread size and a 3/4-inch length under head. The hex drive measures 7/16 inches across flats, compatible with standard combination wrenches and sockets. Silicon bronze fasteners are chosen for their corrosion resistance in wet, marine, and chemical environments where steel fasteners would degrade. This screw uses Unified National Coarse (UNC) threading per inch standard. Installers working on HVAC equipment enclosures, plumbing fixtures, electrical panels, or pool and spa mechanical assemblies will recognize this as a standard imperial-series fastener for general structural and mechanical connections.

This fastener is suited for residential and light commercial trade applications requiring corrosion-resistant hardware. Silicon bronze is a common choice for outdoor equipment, rooftop HVAC mounting hardware, pool mechanical room assemblies, and coastal installations where moisture exposure is a primary concern. Sold in packages of 25, it is appropriate for stocking service vans or shop bins where repeatable fastener availability matters.

Key Features

• Silicon bronze construction provides strong resistance to corrosion and oxidation in wet or marine environments

• 3/4-inch length under head suits shallow-clearance fastening applications
• 7/16-inch hex drive compatible with standard combination wrenches and ratchet sockets
• Sold in a 25-piece package suitable for service stock or job-site replenishment

Compatibility

Designed as a standard 1/4-20 UNC hex head cap screw for use in any application requiring an inch-series, coarse-thread fastener in silicon bronze.

Installation Notes

Installation requires a 7/16-inch combination wrench or socket driver. Power down or de-energize any equipment before replacing or installing fasteners on mechanical or electrical assemblies. Follow applicable torque guidelines from the equipment manufacturer for the specific assembly being serviced. Verify thread engagement depth before final tightening to prevent stripping the mating material.
