Value Collection R57001107 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R57001107 is a fully threaded hex head cap screw designed for general-purpose fastening in applications that require corrosion resistance. It features a 1/4-20 UNC thread profile and measures 4-1/4 inches under the head. Constructed from 18-8 stainless steel with no added coating, this fastener delivers reliable performance in wet, chemical-exposed, or outdoor environments where carbon steel would corrode prematurely. It is suitable for use by maintenance technicians, pipefitters, electricians, and general tradespeople working on mechanical assemblies, equipment panels, and structural connections.

This screw is commonly used in light commercial and residential applications where a full-length threaded grip is required. The fully threaded shank allows engagement along the entire fastener length, making it well-suited for thin materials, through-bolting, and adjustable clamping assemblies. Typical install scenarios include HVAC equipment mounting, electrical enclosure assembly, plumbing fixture attachment, and general mechanical fabrication where stainless steel is specified for corrosion resistance.

Key Features

• 18-8 stainless steel construction provides strong corrosion resistance in wet and outdoor environments
• Fully threaded shank allows maximum thread engagement across the entire 4-1/4 inch length
• 1/4-20 UNC thread standard ensures compatibility with standard inch-series nuts and tapped holes
• Uncoated finish maintains dimensional accuracy and avoids coating interference in close-tolerance applications
• Hex head drive accepts standard hex wrenches and sockets for high-torque installation

Compatibility

Designed as an OEM-style replacement and general-use fastener compatible with any standard 1/4-20 UNC tapped hole or matching hex nut in inch-series fastener applications.

Installation Notes

Installation is performed by maintenance technicians, pipefitters, or general tradespeople using standard hex-drive hand tools or power drivers. Always ensure the mating nut or tapped hole matches the 1/4-20 UNC thread standard before installation to avoid cross-threading. When used in electrical enclosures or equipment, de-energize the assembly before fastener work in accordance with applicable NFPA 70 lockout/tagout procedures. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern.
