Value Collection 837455BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 837455BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, structural connections, and industrial equipment. It features a 5/8-18 UNF thread size with a 2-inch length under head and is fully threaded along its entire shank. The 1/2-inch hex drive allows reliable torque transfer using standard hex keys or socket drive tools. Constructed from alloy steel with a zinc-plated finish, this fastener delivers solid mechanical strength with basic corrosion protection. It is sold individually per package with a minimum order quantity of 10 units.

This screw is suited for precision fastening tasks where UNF fine-thread engagement is required. Fine-thread fasteners are commonly used in applications that demand greater thread engagement strength, reduced axial movement, and tighter clamping force control. Typical install scenarios include machine frames, hydraulic equipment mounting, motor assemblies, and other metal-to-metal connections where a socket cap head profile provides clearance advantages over hex-head configurations. Machinists, millwrights, and maintenance technicians are the primary users of this fastener type.

Key Features

• 5/8-18 UNF fine-thread profile for strong thread engagement and precise clamping control
• 2-inch length under head provides adequate grip range for standard structural and mechanical applications
• Fully threaded shank maximizes thread engagement across the full fastener length
• 1/2-inch hex socket drive for use with standard Allen keys or socket drive tools
• Alloy steel construction for high tensile and shear strength
• Zinc-plated finish meets ASTM B695 for basic corrosion resistance in indoor and light-duty environments

Compatibility

Designed as a standard UNF hex socket cap screw for use in any application requiring a 5/8-18 thread pitch. Verify thread pitch, length under head, and drive size against the assembly specification before installation.

Installation Notes

Installation is performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket driver. Ensure mating threads are clean and free of debris before driving the fastener. Do not exceed the torque rating of the mating material, and never use impact tools on fine-thread fasteners in blind or tapped holes without verifying thread condition. De-energize, depressurize, or lock out equipment before replacing fasteners in live mechanical assemblies.
