Value Collection R57001180 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R57001180 is a fully threaded hex head cap screw designed for general-purpose fastening applications requiring corrosion resistance. Manufactured from 18-8 stainless steel with a bright uncoated finish, this fastener measures 5/8-11 thread size with a 3/4-inch length under the head. The UNC (Unified National Coarse) thread standard ensures broad compatibility with standard tapped holes and hex nuts. This screw is suited for mechanical assemblies, equipment mounting, and structural connections where stainless steel is specified for oxidation or chemical resistance. Tradespeople and maintenance technicians working in wet, coastal, or chemically exposed environments commonly specify 18-8 stainless fasteners for long service life.

This hex head cap screw is appropriate for use in HVAC equipment mounting, plumbing fixture installation, pool and spa equipment assembly, and general industrial or commercial maintenance work. The coarse UNC thread pattern allows faster installation in applications where fine thread is not required. At 5/8-11, this fastener accepts standard 15/16-inch hex tooling and is compatible with correspondingly tapped metal or structural components.

Key Features

• 18-8 stainless steel construction provides corrosion and oxidation resistance in wet or chemically exposed environments
• Fully threaded shank along the full length under the head for maximum thread engagement
• 5/8-11 UNC thread for compatibility with standard coarse-thread tapped holes and nuts
• Bright uncoated finish — no plating that could compromise dimensions or introduce galvanic concerns with stainless mating hardware
• 3/4-inch length under head suits shallow fastening applications and thin material stacks

Compatibility

Designed as a standard UNC hex head cap screw for use with any 5/8-11 tapped hole or compatible hex nut in general mechanical, HVAC, plumbing, pool, or industrial assembly applications.

Installation Notes

Installation should be performed by qualified tradespeople using an appropriately sized hex wrench or socket driver. Ensure mating threads are clean and free of debris before installation. Avoid mixing stainless fasteners with carbon steel hardware in the same joint to minimize galvanic corrosion risk. Torque to the specification required by the assembly or equipment manufacturer.
