Value Collection 307350BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 307350BR is a hex socket cap screw designed for high-strength fastening applications across mechanical, industrial, and structural assemblies. It features a 5/8-18 UNF thread size with a 1 inch length under head and is fully threaded. Driven with a 1/2 inch hex key, this fastener is manufactured from alloy steel and finished with a black oxide coating that provides moderate corrosion resistance and a clean, low-reflectance appearance. It meets ASTM A574 standards, which specify the mechanical property requirements for socket cap screws. This fastener is installed by machinists, millwrights, maintenance technicians, and mechanical contractors.

This screw is suited for general industrial and mechanical applications where a recessed hex drive and high tensile strength are required. Typical uses include machine component assembly, fixture fabrication, tooling, and equipment maintenance. The fine 18 TPI thread pitch makes it well suited for applications requiring precise torque control and strong thread engagement in steel or other ferrous materials.

Key Features

• 5/8-18 UNF fine thread for precise torque control and strong thread engagement
• Fully threaded for maximum grip across the entire shaft length
• 1/2 inch hex socket drive compatible with standard hex keys and drive tools
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide finish provides moderate corrosion protection and reduces light reflection
• 1 inch length under head suitable for a wide range of fastening depths

Compatibility

Designed as a standard ASTM A574 hex socket cap screw for use in any application requiring a 5/8-18 UNF fully threaded fastener with a 1/2 inch hex drive.

Installation Notes

Install using a 1/2 inch hex key or socket drive tool. Ensure mating threads are clean and free of debris before installation. Do not exceed the rated torque range for the fastener grade and material being joined. When working in corrosive environments, evaluate whether black oxide finish provides sufficient protection or if additional coating is needed.
