Value Collection R80324994 Hex Head Cap Screw 5/8-18

Product Description

The VALUE COLLECTION R80324994 is a fully threaded hex head cap screw engineered for industrial and trade applications where corrosion resistance is critical. Machined to a 5/8-18 UNF thread specification and measured 2 inches under the head, this fastener is produced from Grade 316 stainless steel and left uncoated to preserve its base material properties. Grade 316 stainless provides superior resistance to chlorides and harsh chemical environments compared to standard 304 stainless, making it a preferred choice in marine, chemical processing, food service, and outdoor structural applications.

This fastener is suited for residential and commercial mechanical, plumbing, and structural installations where exposure to moisture, salt, or corrosive media demands a high-alloy stainless fastener. The UNF fine-thread profile offers greater thread engagement and improved tension-bearing capacity compared to coarse-thread equivalents of the same diameter, which is useful when working with thin-walled materials or applications requiring precise torque control.

Key Features

• Grade 316 stainless steel construction for superior corrosion resistance in harsh and wet environments
• 5/8-18 UNF fine-thread profile for improved thread engagement and holding strength
• Fully threaded along the 2-inch under-head length for maximum fastening flexibility
• Uncoated finish preserves base 316 stainless properties with no coating to degrade or flake
• Hex head drive for standard wrench and socket installation

Compatibility

Designed as an OEM-style replacement or standard-service fastener for any application requiring a 5/8-18 UNF fully threaded hex head cap screw in Grade 316 stainless steel.

Installation Notes

Installation is performed by mechanical, plumbing, or structural trades using a standard hex wrench or socket. Always verify thread engagement and torque requirements per the equipment manufacturer specifications or applicable code before final tightening. Inspect mating threads for damage or contamination before installation to prevent galling, which is common with stainless fasteners. Apply an anti-seize compound rated for stainless steel if the fastener may need to be removed in the future.
