Value Collection 837451BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 837451BR is a hex socket cap screw designed for applications requiring a secure, high-torque fastener driven with a hex key. Sized at 5/8-18 UNF with a 1-1/2 inch length under head, this screw is fully threaded and manufactured from alloy steel with a zinc-plated finish for corrosion resistance. The 1/2-inch hex drive allows for high-torque installation with standard hex keys or socket tools. Meeting ASTM B695 standards, this fastener is suited for mechanical assemblies, machinery maintenance, and general industrial or trade use where a recessed-drive cap screw is required.

This screw is commonly used in mechanical, industrial, and trade applications where a flush or recessed fastener head is needed. It is appropriate for use in metal-to-metal assemblies, equipment brackets, and structural components. The fine UNF thread pitch provides strong thread engagement in applications where vibration resistance or precise clamping force is important. Maintenance technicians, machinists, and trade professionals across HVAC, plumbing, and general mechanical service will encounter this fastener type in field and shop settings.

Key Features

• 5/8-18 UNF fine thread for strong engagement and vibration resistance
• 1-1/2 inch length under head, fully threaded along entire shank
• Alloy steel construction provides high tensile strength
• Zinc-plated finish meets ASTM B695 for corrosion protection
• 1/2-inch hex socket drive compatible with standard hex keys and socket drivers

Compatibility

Designed as a standard 5/8-18 UNF hex socket cap screw suitable for use in mechanical assemblies, equipment maintenance, and industrial applications requiring this thread size and drive type.

Installation Notes

Install using a 1/2-inch hex key or hex bit socket with appropriate torque for 5/8-18 UNF alloy steel fasteners per the assembly specification. De-energize and lock out equipment before replacing or installing fasteners on mechanical systems. Inspect threads on both the screw and mating component before installation to ensure clean engagement. Do not over-drive; alloy steel cap screws are high-strength but can strip if thread condition is compromised.
