Value Collection R68449682 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION R68449682 is a hex socket cap screw designed for high-strength fastening in mechanical, industrial, and structural applications. The screw features a 3/4-10 UNC thread size and a 3-inch length under head, providing substantial grip in thick material assemblies. Drive engagement is accomplished with a 5/8-inch hex key. Constructed from 18-8 stainless steel, this fastener resists corrosion in wet, chemical-exposed, and outdoor environments. It is a standard-fitment screw commonly installed by machinists, millwrights, pipefitters, and maintenance technicians in equipment assembly, pipe flange work, and structural fastening tasks.

This socket cap screw is suited for applications where a flush or recessed fastener head is required and torque must be applied with an Allen-style hex key rather than a conventional wrench or socket. Typical use cases include mounting machine components, securing brackets and flanges, and bolting heavy equipment frames. The 3/4-10 UNC coarse thread pattern provides fast engagement and reliable clamping force in ferrous and non-ferrous base materials. Industries served include general manufacturing, water treatment, food processing, and marine environments where stainless steel is specified for corrosion resistance.

Key Features

• 3/4-10 UNC coarse thread for fast engagement and strong clamping force
• 3-inch length under head accommodates thick material stacks and flanged joints
• 5/8-inch hex drive allows high torque input with standard Allen or hex key tooling
• 18-8 stainless steel construction provides corrosion resistance in wet and chemical environments
• Socket cap head profile enables installation in recessed or confined fastening locations

Compatibility

Designed as a standard 3/4-10 UNC hex socket cap screw suitable for use in any tapped or through-hole assembly requiring a 3/4-10 coarse thread fastener with a recessed hex drive head.

Installation Notes

Installation requires a 5/8-inch hex key or Allen driver in good condition to prevent rounding the drive socket. Ensure the mating threaded hole or nut is clean and free of debris before assembly. Apply thread lubricant or anti-seize compound as required by the application to prevent galling, which is a known risk with stainless steel fasteners. Torque to the value specified by the equipment manufacturer or applicable engineering standard.
