Value Collection VS1026PR Hex Head Cap Screw 1/4-20 X 7/8 in

Product Description

The VALUE COLLECTION VS1026PR is a 1/4-20 UNC fully threaded hex head cap screw manufactured from silicon bronze alloy grade C651. It measures 7/8 inches in length under the head with a 7/16-inch hex drive and carries a bright, uncoated finish. Compliant with ASME B18.2.1, this fastener delivers the corrosion resistance silicon bronze is known for in marine, plumbing, and wet-environment applications. Licensed tradespeople and maintenance professionals select this screw where galvanic compatibility with copper alloys or seawater exposure is a primary design requirement.

This cap screw is suited for use in marine hardware assemblies, HVAC condensate and water-side connections, plumbing fixtures, pool and spa equipment, and other environments where ferrous fasteners would corrode prematurely. The silicon bronze C651 material also makes it a common choice in electrical grounding assemblies and architectural metalwork where appearance and corrosion performance both matter. It is installed by plumbers, marine mechanics, electricians, and general maintenance technicians working on copper-alloy or bronze-component assemblies.

Key Features

• Silicon bronze C651 material provides strong corrosion resistance in marine and wet-environment service
• Fully threaded 1/4-20 UNC thread form for maximum engagement across the full fastener length
• Bright, uncoated finish preserves as-machined surface and dimensional accuracy
• Meets ASME B18.2.1 dimensional standard for hex head cap screws
• 7/16-inch hex drive is compatible with standard wrenches and sockets

Compatibility

Designed as an OEM-style replacement or maintenance fastener for assemblies requiring 1/4-20 UNC fully threaded hex head cap screws in silicon bronze.

Installation Notes

Install with a 7/16-inch wrench or socket driver. De-energize and isolate any system before replacing fasteners on electrical or pressurized components. Avoid mixing with dissimilar metals in environments where galvanic corrosion is a concern, and follow applicable ASME or NEC guidelines for the specific assembly type.
