Value Collection 88547104 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 88547104 is a 5/8-11 UNC hex socket cap screw designed for high-strength fastening in industrial and mechanical assemblies. The screw measures 4 inches in length under the head and uses a 1/2 inch hex drive for installation with a standard hex key or socket driver. It is partially threaded, which concentrates clamping load and improves shear strength in bolted joints. Constructed from alloy steel with a black oxide finish, it offers solid mechanical performance and moderate corrosion resistance in protected environments. Maintenance technicians, millwrights, and machine assemblers are the typical installers for fasteners of this type.

This screw suits applications in structural and mechanical assemblies where a recessed drive profile is preferred over an external hex head. Typical use cases include machinery frames, equipment housings, jigs, fixtures, and general industrial fabrication. The partially threaded shank is well suited for through-bolt and clearance-hole configurations where the unthreaded portion provides a precise bearing surface. Each package contains 3 screws, making it appropriate for small-quantity service work or replacement jobs.

Key Features

• 5/8-11 UNC thread specification for standard inch-series threaded holes
• 4 inch length under head accommodates medium- to heavy-gauge assemblies
• Partially threaded shank improves shear resistance and clamping force
• 1/2 inch hex socket drive accepts standard hex keys and socket drivers
• Alloy steel construction provides high tensile and yield strength
• Black oxide finish offers mild corrosion protection in dry or lightly oiled environments

Compatibility

Designed as a standard 5/8-11 UNC hex socket cap screw for use in any inch-series tapped hole or threaded insert conforming to that thread specification.

Installation Notes

Installation is typically performed by millwrights, maintenance technicians, or mechanical assemblers using a 1/2 inch hex key or T-handle driver. Ensure the mating tapped hole is clean and free of debris before threading the fastener. Apply thread lubricant or anti-seize as required by the assembly specification to achieve accurate torque values. Always de-energize and lock out equipment before servicing fasteners on machinery in accordance with applicable OSHA lockout/tagout procedures.
