Value Collection R68449068 Hex Socket Cap Screw 5/8-11

Product Description

The VALUE COLLECTION R68449068 is a hex socket cap screw designed for threaded fastening applications requiring a clean, recessed drive profile. This fastener features a 5/8-11 UNC thread form, a 1/2-inch hex drive socket, and a 4-inch length under head. It is manufactured from 18-8 stainless steel, providing corrosion resistance in wet or chemically exposed environments. The socket cap head allows installation in recessed or tight-clearance applications where a standard hex bolt head would not fit. Mechanical contractors, millwrights, pipefitters, and maintenance technicians routinely specify this fastener style where a flush or low-profile fastened joint is required.

This screw is suited for light industrial, commercial, and mechanical applications including equipment mounting, pump and motor assembly, pipe support bracketing, and general structural fastening. The 18-8 stainless steel construction makes it appropriate for outdoor, marine-adjacent, or moisture-prone installations. It is sold as a single unit, making it a practical replacement or retrofit fastener for existing assemblies requiring an exact-match replacement.

Key Features

• 5/8-11 UNC thread form provides a coarse-thread engagement suitable for general mechanical assemblies
• 4-inch length under head accommodates thicker material stacks and deep-clearance fastening situations
• 1/2-inch hex socket drive works with standard hex keys and socket drivers used in the trade
• 18-8 stainless steel construction resists rust and corrosion in wet or chemically active environments
• Recessed socket cap head profile allows use in counterbored holes and tight-clearance installations

Compatibility

Designed as an OEM-style replacement or retrofit hex socket cap screw for mechanical, industrial, and commercial assemblies requiring a 5/8-11 UNC threaded fastener with a 4-inch length under head and 1/2-inch hex drive.

Installation Notes

Installation is typically performed by mechanical, pipefitting, or maintenance trades using a calibrated hex key or socket driver sized to 1/2 inch. Verify thread engagement depth and ensure the mating tapped hole or nut is rated for the load before tightening. Do not overtighten stainless steel fasteners into stainless tapped holes without appropriate anti-galling compound, as galling can permanently seize the joint. Follow applicable mechanical codes and equipment manufacturer torque guidance for the specific assembly.
