Value Collection R57001196 Hex Head Cap Screw 1/4-20

Product Description

The VALUE COLLECTION R57001196 is a 1/4-20 UNC hex head cap screw measuring 3-3/4 inches under the head, manufactured from 18-8 stainless steel with no surface coating applied. The partially threaded shank allows for a bearing surface against fastened material, which is useful in applications requiring clamping load without full thread engagement along the entire length. At 0.2 pounds, this is a standard inch-series fastener suited for assembly, maintenance, and repair work across HVAC equipment, plumbing fixtures, electrical enclosures, and pool equipment installations where corrosion resistance is a priority.

This cap screw is commonly used in light industrial and commercial trade applications where 18-8 stainless steel provides adequate resistance to moisture, mild chemicals, and outdoor exposure. Typical uses include securing panels, brackets, and flanges on HVAC units, pump housings, and electrical enclosures. The UNC thread form is the standard coarse-thread specification used across most inch-series fastener applications in the trades.

Key Features

• 1/4-20 UNC coarse thread for broad compatibility with standard inch-series tapped holes
• 3-3/4 inch length under head provides clamping depth for thicker assemblies
• Partially threaded shank delivers a bearing surface for improved clamping in bolted joints
• 18-8 stainless steel construction resists corrosion in wet and outdoor environments
• Uncoated finish — no plating or coating that could interfere with torque values or galvanic compatibility assessments

Compatibility

Designed as a standard inch-series hex head cap screw for use in any application requiring a 1/4-20 UNC threaded fastener with a 3-3/4 inch length under head.

Installation Notes

Installation should be performed by a qualified technician familiar with fastener torque specifications appropriate to the joint material and application. Always consult the equipment manufacturer torque table for 1/4-20 stainless steel fasteners, as over-torquing can gall stainless threads. Use a hex wrench or socket driver sized for a standard 1/4-20 hex head. When fastening into dissimilar metals, evaluate galvanic compatibility before selecting stainless steel hardware.
