Value Collection R46416802 Hex Head Cap Screw 5/8-18 X 4 in

Product Description

The VALUE COLLECTION R46416802 is a partially threaded hex head cap screw designed for fastening applications that require corrosion-resistant hardware. Manufactured from 18-8 stainless steel with no surface coating, this fastener delivers reliable performance in wet, chemical-exposure, or outdoor environments where carbon steel hardware would degrade. The screw measures 4 inches under the head with a 5/8-18 UNF thread specification, making it suitable for fine-thread connections that demand precise torque retention and vibration resistance. It is sold individually and suited for use by maintenance technicians, pipefitters, plumbers, and general tradespeople working with stainless fastener assemblies.

This hex head cap screw fits inch-measurement applications calling for a 5/8-18 UNF fine-thread fastener in a 4-inch under-head length. Partially threaded shanks are common in structural connections where the unthreaded portion bears shear load or where clamping force must be distributed across a smooth bearing surface. Typical install scenarios include mechanical equipment mounts, plumbing flange assemblies, pump housings, and general industrial maintenance tasks requiring stainless hardware.

Key Features

• 18-8 stainless steel construction resists corrosion in wet and chemically active environments
• Partially threaded shank supports shear-load applications and clean clamping surfaces
• 5/8-18 UNF fine thread provides tighter thread engagement and improved torque retention versus coarse thread
• Uncoated finish ensures compatibility with stainless nuts and flanged hardware without galling concerns from dissimilar coatings
• 4-inch under-head length suits deeper fastening applications and thicker material stacks
• Inch measurement system; sold as a single unit with no minimum order quantity above one piece

Compatibility

Designed as an OEM-style replacement or direct-use fastener for any application requiring a 5/8-18 UNF partially threaded hex head cap screw in 18-8 stainless steel, inch measurement system.

Installation Notes

Install using a standard hex wrench or socket sized for a 5/8-inch hex head cap screw. De-energize and lock out any associated equipment before fastener replacement in live mechanical systems. Apply anti-seize compound rated for stainless steel to prevent galling between stainless mating threads. Verify thread engagement depth and confirm the mating nut or tapped hole is rated for UNF 5/8-18 pitch before torquing.
