Value Collection R63033486 Hex Head Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R63033486 is a 5/8-11 UNC hex head cap screw with a 3-1/2 inch length under head, manufactured from Grade 316 stainless steel. Grade 316 stainless offers superior corrosion resistance compared to Grade 304, making it well suited for wet, chemical, or marine environments. The hex drive measures 15/16 inches across the flats. This fastener is sold individually and is used across a range of industrial, mechanical, and construction applications wherever a fully threaded or partially threaded inch-series cap screw is required.

This cap screw is appropriate for use in plumbing, HVAC equipment mounting, pool and spa mechanical assemblies, and general industrial installations where corrosion resistance is a priority. The 5/8-11 UNC thread form is a standard coarse-thread designation compatible with commonly available hex nuts, lock nuts, and threaded inserts of the same thread size. It is a common choice for fastening equipment frames, pipe supports, pump housings, and structural brackets in corrosive or outdoor service environments.

Installation Notes

Installation is performed using a standard 15/16 inch combination wrench or socket driver. De-energize, depressurize, or shut off any system before fastening or removing structural hardware. Do not mix stainless steel fasteners with dissimilar metals in applications where galvanic corrosion is a concern. Follow applicable mechanical and structural codes for required fastener torque and thread engagement depth.
