Value Collection 3TBT904C0112 Hex Cap Screw 1/4-20

Product Description

The VALUE COLLECTION 3TBT904C0112 is a fully threaded hex head cap screw designed for fastening applications that demand corrosion resistance and dimensional consistency. Built from Grade 316 stainless steel with no finish coating, this fastener carries a 1/4-20 UNC thread and a 1-3/4 inch length under the head. The 316 alloy provides superior resistance to chlorides and harsh chemicals compared to 304 stainless, making it a preferred choice in marine, chemical processing, plumbing, and HVAC environments where moisture or corrosive agents are present. Tradespeople and maintenance technicians reach for this screw when the application demands long-term holding strength without rust or galvanic concerns.

This screw is suited for residential and commercial mechanical installations, equipment mounting, and general structural fastening tasks across HVAC, plumbing, pool, and industrial service work. The fully threaded shank provides maximum thread engagement across the full 1-3/4 inch grip length, which is useful in thin-material assemblies or when threading directly into a tapped hole. Licensed tradespeople working in corrosive or wet environments routinely specify 316 stainless hardware to meet project or code requirements.

Key Features

• Grade 316 stainless steel construction for high corrosion resistance in wet and chemical environments
• Fully threaded shank across the full 1-3/4 inch length under head for maximum thread engagement
• 1/4-20 UNC thread form for broad compatibility with standard inch-system tapped holes and nuts
• Uncoated finish preserves 316 alloy surface properties without risk of coating delamination
• Hex head drive for use with standard wrenches or hex sockets

Compatibility

Designed for use with standard 1/4-20 UNC tapped holes, hex nuts, and threaded inserts conforming to inch-system fastener standards.

Installation Notes

Installation is performed by mechanical and maintenance tradespeople using standard open-end, box, or socket wrenches sized for a 1/4 inch hex head fastener. Always verify thread engagement depth before applying final torque to avoid stripping threads in soft base materials. De-energize or depressurize any system before replacing or installing fasteners on pressurized components. Avoid mixing stainless fasteners with dissimilar metals in submerged or high-humidity applications to minimize galvanic corrosion risk.
