Value Collection 837449BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 837449BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Manufactured from alloy steel with a zinc-plated finish for corrosion resistance, this fastener features a 5/8-18 UNF thread size and a 1-1/4 inch length under head. Drive engagement is achieved with a 1/2 inch hex socket. The fully threaded shank provides maximum thread engagement throughout the grip length. This type of fastener is commonly installed by millwrights, maintenance mechanics, and assemblers working in manufacturing, equipment fabrication, and field repair environments.

This screw is suited for use in precision mechanical assemblies, machine frames, tooling fixtures, and structural connections requiring fine-thread engagement. The 5/8-18 UNF thread pitch is a fine-thread designation, making it appropriate for applications where vibration resistance or precise torque control is important. The zinc plating provides a baseline level of corrosion protection suitable for indoor and light-duty outdoor environments. Sold in minimum order quantities of 10 units, this fastener is stocked for maintenance, repair, and operations (MRO) use as well as production-line applications.

Key Features

• 5/8-18 UNF fine-thread specification for vibration-resistant fastening
• 1-1/4 inch length under head with fully threaded shank for maximum engagement
• 1/2 inch hex socket drive for high-torque installation with standard tooling
• Alloy steel construction for superior tensile and shear strength
• Zinc-plated finish provides corrosion protection in indoor and light-duty environments
• Meets ASTM B695 fastener standard

Compatibility

Designed as a standard 5/8-18 UNF hex socket cap screw suitable for use in mechanical assemblies, equipment frames, and tooling fixtures that require a fine-thread alloy steel fastener with a hex socket drive.

Installation Notes

Installation requires a 1/2 inch hex key or socket driver. Power down or de-energize any equipment before servicing fastened assemblies. Ensure mating threads are clean and free of debris before installation. Do not exceed the torque rating specified by the equipment manufacturer for this thread size and material grade.
