Value Collection 203062 Hex Head Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 203062 is a fully threaded hex head cap screw designed for fastening applications that demand corrosion resistance and reliable clamping strength. Sized at 5/8-11 UNC with a 3-inch length under head, this fastener features a 15/16-inch hex drive and is manufactured from Grade 316 stainless steel with an uncoated finish. Grade 316 stainless offers superior resistance to chlorides and chemical exposure compared to standard 304 stainless, making it a common choice in marine, plumbing, and industrial environments. Tradespeople and maintenance technicians reach for this screw when the application demands a durable, full-engagement thread pattern with broad hex drive access.

This fastener is appropriate for use in residential and light commercial installations where a coarse 5/8-11 UNC thread pattern is required. Typical applications include structural bracketing, equipment mounting, and flange assembly in wet or corrosive environments such as pump rooms, pool mechanical areas, and outdoor utility installations. Its fully threaded profile maximizes thread engagement across the full length of the fastener, which is especially useful in thin material or through-bolt configurations.

Key Features

• Fully threaded 5/8-11 UNC coarse thread for maximum engagement
• Grade 316 stainless steel construction for high corrosion resistance in wet or chemical-exposed environments
• 3-inch length under head suits a range of material stack thicknesses
• 15/16-inch hex drive compatible with standard sockets and wrenches
• Uncoated finish eliminates coating compatibility concerns in stainless applications

Compatibility

Designed as a standard 5/8-11 UNC hex head cap screw suitable for use wherever a Grade 316 stainless steel fully threaded fastener of this thread size and length is specified.

Installation Notes

Installation should be performed by a qualified tradesperson or mechanic using a properly sized 15/16-inch socket or open-end wrench. Torque to the fastener specification required by the assembly or governing code — do not estimate. Apply anti-seize compound when joining dissimilar metals or in high-moisture environments to prevent galling, which is common with stainless steel fasteners. Ensure mating threads are clean and free of debris before installation.
