Value Collection R57001171 Hex Head Cap Screw 1/2-13

Product Description

The VALUE COLLECTION R57001171 is a fully threaded hex head cap screw designed for general industrial and mechanical fastening applications. Manufactured from 18-8 stainless steel, this fastener delivers solid corrosion resistance in wet, humid, or mildly corrosive environments. The 1/2-13 UNC thread size and 4-3/4 inch length under head make it suitable for through-bolting, flanged connections, and structural assemblies where a longer grip length is required. The hex drive head accepts standard 6-point sockets and wrenches, allowing torque to be applied efficiently in both open and confined installation areas. This screw ships individually but is subject to a minimum order quantity.

This fastener is suited for use in plumbing, HVAC equipment mounting, pool equipment installation, electrical enclosure assembly, and general mechanical fabrication. The fully threaded shank provides thread engagement along the entire length under the head, which is particularly useful when fastening thin materials or when a nut must be positioned at any point along the shank. The uncoated 18-8 stainless steel finish is appropriate for outdoor, marine-adjacent, and high-humidity service conditions common in trade environments.

Key Features

• Fully threaded shank provides maximum thread engagement along entire fastener length
• 18-8 stainless steel construction offers corrosion resistance in wet and humid environments
• 1/2-13 UNC thread standard ensures broad compatibility with standard nuts and threaded inserts
• 4-3/4 inch length under head suits through-bolting and deeper material stacks
• Hex head design accepts 6-point socket or wrench for reliable torque application
• Uncoated finish maintains dimensional consistency and avoids coating thickness variation at threads

Compatibility

Designed as a standard 1/2-13 UNC fully threaded hex head cap screw compatible with any 1/2-13 nut, coupling nut, or threaded insert following Unified National Coarse thread standards.

Installation Notes

Installation is appropriate for mechanics, millwrights, plumbers, and HVAC technicians performing equipment mounting or structural fastening. De-energize and lock out all associated equipment before working in proximity to electrical components. Use a calibrated torque wrench appropriate for the joint material and application; consult applicable codes or engineering specifications for target torque values. Apply a compatible anti-seize compound when joining stainless steel fasteners to stainless steel threaded components to prevent galling.
