Value Collection -48548-6 Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION -48548-6 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and equipment maintenance. It features a 5/8-18 UNF thread size with a 2-3/4 inch length under head and is partially threaded for precise clamping in controlled-depth bores. The 1/2 inch hex drive is compatible with standard hex keys and socket drive tools. Constructed from alloy steel with a black oxide finish, this screw delivers corrosion resistance and meets ASME/ANSI B18.3 and ASTM A574 standards. Machinists, millwrights, and maintenance technicians regularly specify this fastener type for structural and load-bearing connections.

This screw is suited for use in industrial machinery, fixtures, die sets, and precision equipment where fine-thread UNF engagement is required for vibration resistance and torque retention. The partially threaded shank provides a smooth bearing surface in clearance holes, making it appropriate for assemblies requiring tight positional tolerances. Minimum order quantity is 10 pieces.

Key Features

• 5/8-18 UNF fine thread for high vibration resistance and precise torque control
• 2-3/4 inch length under head with partial threading for clearance-hole assemblies
• 1/2 inch hex socket drive compatible with standard hex keys and drive tools
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides mild corrosion protection and reduces light reflection
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in any application requiring a 5/8-18 UNF partially threaded fastener with a 1/2 inch hex drive.

Installation Notes

Installation is performed using a 1/2 inch hex key or socket driver. Ensure mating threaded holes are clean and free of debris before installation. Follow applicable torque specifications from your engineering drawings or fastener reference tables for ASTM A574 alloy steel cap screws. De-energize and lock out any equipment before performing fastener service on live machinery per OSHA lockout/tagout procedures.
