Value Collection VS1108PS Hex Cap Screw 3/8-16 Silicon Bronze

Product Description

The VALUE COLLECTION VS1108PS is a hex head cap screw designed for fastening applications that require corrosion resistance in wet, marine, or chemically active environments. Manufactured from silicon bronze alloy grade C651, this fully threaded fastener follows a 3/8-16 UNC thread pattern with a 1-1/4 inch length under head. The bright, uncoated finish maintains the natural surface of the alloy. It meets ASME B18.2.1 dimensional standards, making it a reliable choice for structural and mechanical assemblies where bronze fasteners are specified. Licensed tradespeople and maintenance professionals working near saltwater, pool equipment, or plumbing systems commonly select silicon bronze hardware for its long-term durability under corrosive conditions.

This cap screw is suited for residential and commercial applications where standard steel fasteners would corrode prematurely. Typical use cases include dock hardware, pool and spa equipment, marine plumbing fixtures, and coastal HVAC installations. The 9/16 inch hex drive size is compatible with standard combination wrenches and hex sockets. The fully threaded shaft provides consistent thread engagement across the full grip length, which is useful in thin-material or through-bolt installations.

Compatibility

Designed as an OEM-style or aftermarket replacement fastener for assemblies specifying 3/8-16 UNC fully threaded hex head cap screws in silicon bronze.

Installation Notes

Installation should be performed by a qualified tradesperson familiar with fastener torque requirements for bronze alloys, as silicon bronze is softer than steel and susceptible to galling if over-torqued. Power down or depressurize any system before replacing fasteners in pressurized plumbing or HVAC enclosures. Use a calibrated torque wrench and apply an appropriate anti-seize compound if fastening into a dissimilar metal to prevent galvanic corrosion. Follow applicable codes such as IPC or NEC when installing in plumbing or electrical enclosure applications.
