Value Collection 837453BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 837453BR is a hex socket cap screw designed for high-strength mechanical fastening applications. It features a 5/8-18 UNF thread form, a 1-3/4 inch length under head, and a 1/2 inch hex drive. The fastener is fully threaded along its shank, manufactured from alloy steel, and finished with a zinc plating that provides baseline corrosion resistance. This screw meets ASTM B695 standards and is suited for precision assembly work where fine-thread engagement and reliable clamping load are required. Machinists, millwrights, and maintenance technicians are the typical installers.

This screw is used in industrial, mechanical, and structural assembly scenarios where a fine-thread UNF fastener is specified. Fine-thread fasteners like this 5/8-18 are commonly chosen over coarse-thread variants when higher thread engagement strength, better vibration resistance, or closer adjustment control is needed. Typical applications include machine frames, equipment mounting, and structural steel assembly in both manufacturing and maintenance environments. The zinc coating makes it suitable for indoor and light-exposure installations where mild corrosion resistance is acceptable.

Key Features

• 5/8-18 UNF fine thread for high engagement strength and vibration resistance
• 1-3/4 inch length under head for reliable grip in standard fastening applications
• Fully threaded shank provides maximum thread engagement throughout the length
• 1/2 inch hex socket drive for use with standard hex keys and socket drive tools
• Alloy steel construction delivers high tensile and shear strength
• Zinc-plated finish per ASTM B695 for baseline corrosion protection

Compatibility

Designed as a standard 5/8-18 UNF hex socket cap screw for use in any application requiring a fully threaded fine-thread fastener with a 1/2 inch hex drive, conforming to ASTM B695.

Installation Notes

Install using a calibrated torque wrench and the appropriate 1/2 inch hex key or socket bit; do not over-torque, as alloy steel fine-thread fasteners can strip or gall mating threads if driven beyond specification. Ensure mating threads are clean and free of debris before installation. When replacing fasteners in structural or load-bearing assemblies, follow the original equipment manufacturer torque specifications and applicable codes.
