Value Collection R57001095 Hex Socket Cap Screw 5/8-18

Product Description

The VALUE COLLECTION R57001095 is a hex socket cap screw in 5/8-18 UNF threading with a 2-inch length under head. It is driven with a 1/2-inch hex key and manufactured from 18-8 stainless steel with a bright, uncoated finish. This fastener is used across industrial, mechanical, and trade applications where corrosion resistance and clean torque delivery are required. Licensed tradespeople and skilled assemblers install this type of screw when tensile strength and rust resistance are priorities in the joint.

This screw suits applications in plumbing equipment assemblies, HVAC bracket mounting, pump housings, and general mechanical assemblies where stainless hardware is specified. The 5/8-18 UNF thread pitch is a fine-thread standard, making it appropriate for joints requiring precise clamping load or use in materials where coarse threading would reduce pullout strength. It is sold individually and compatible with standard 1/2-inch hex drive tools.

Key Features

• 18-8 stainless steel construction provides corrosion resistance in wet or outdoor environments
• 5/8-18 UNF fine-thread form for precise clamping and higher torque resistance compared to coarse thread
• 2-inch length under head suits medium-depth fastening applications
• Bright, uncoated finish — no plating that could flake or add dimensional variance
• 1/2-inch hex socket drive for use with standard Allen keys or hex bit drivers

Compatibility

Designed as a standard 5/8-18 UNF hex socket cap screw for use in any assembly requiring that thread form and a 2-inch grip length in stainless steel.

Installation Notes

Installation requires a 1/2-inch hex key or socket hex bit. Verify thread engagement depth and mating material before installation to avoid galling, which is common with stainless fasteners — apply anti-seize compound to threads when torquing stainless-to-stainless joints. Always de-energize or depressurize any system before accessing fastened components. Follow applicable mechanical assembly standards for fastener torque specifications based on joint design.
