Value Collection R57001267 Hex Head Cap Screw 5/8-11

Product Description

The Value Collection R57001267 is a partially threaded hex head cap screw engineered for structural and mechanical fastening applications. It features a 5/8-11 UNC thread size with a 7-1/2 inch length under head, constructed from 18-8 stainless steel with no coating applied. The 18-8 stainless grade provides solid corrosion resistance in wet, outdoor, and mildly corrosive environments. The partial thread design allows the unthreaded shank to bear shear loads, making it well suited for clamping and load-bearing joints where full thread engagement is not required. Installers working in plumbing, HVAC equipment mounting, pool mechanical rooms, or general industrial assembly will find this fastener appropriate for standard inch-series hardware.

This cap screw is intended for use in assemblies requiring a coarse UNC thread pattern with a standard hex drive. The 5/8-11 thread designation indicates 11 threads per inch on a 5/8 inch diameter shank. Partial threading leaves a smooth bearing shank below the head, which is common in flange bolting, equipment mounting, and structural connections. This fastener is sold individually and is appropriate for single-unit replacement or small-quantity service work across residential and commercial trade applications.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet and outdoor environments
• Partially threaded shank supports shear load transfer in structural and clamping joints
• 5/8-11 UNC coarse thread for compatibility with standard inch-series nuts and tapped holes
• 7-1/2 inch length under head accommodates deep through-bolt applications
• Uncoated finish — no plating or treatment that could interfere with stainless-to-stainless or stainless-to-metal contact surfaces

Compatibility

Designed as a standard inch-series hex head cap screw for use with any 5/8-11 UNC threaded nut, insert, or tapped hole requiring a partially threaded fastener in 18-8 stainless steel.

Installation Notes

Installation is typically performed by maintenance technicians, pipefitters, or mechanical contractors using a standard hex wrench or socket set sized for the 5/8 inch hex head. De-energize and depressurize any equipment before replacing or installing structural fasteners. Apply an anti-seize compound when fastening stainless steel to stainless steel to prevent galling during torque-up. Follow applicable mechanical and structural codes for proper torque and joint requirements.
