Value Collection 307370BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 307370BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. The screw features a 5/8-18 UNF thread size and measures 2.5 inches in length under the head, with partial threading along the shank. Manufactured from alloy steel and finished with a black oxide coating, it meets ASTM A574 standards for mechanical strength and corrosion resistance. Installation requires a 1/2-inch hex drive. This fastener is suited for machinists, maintenance technicians, and fabricators working with precision assemblies.

This socket cap screw is appropriate for residential and commercial mechanical, industrial, and equipment maintenance applications. Its fine UNF thread pitch makes it well suited for high-vibration environments or assemblies requiring close tolerances and strong clamp load. The black oxide finish provides moderate corrosion resistance for indoor and light-exposure use. Sold individually, with a minimum order quantity of 10 units per order.

Key Features

• 5/8-18 UNF fine-thread for strong clamp load and vibration resistance
• 2.5 inches length under head with partial threading
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish for moderate corrosion resistance
• 1/2-inch hex socket drive for positive torque engagement

Compatibility

Designed as a standard ASTM A574 hex socket cap screw suitable for 5/8-18 UNF tapped holes in mechanical assemblies, industrial equipment, and fabricated structures requiring a partially threaded alloy steel fastener.

Installation Notes

Installation is performed by machinists, millwrights, and maintenance technicians using a 1/2-inch hex key or socket drive. De-energize and lock out all equipment before servicing any fastened assembly. Ensure the mating tapped hole is clean and free of debris before thread engagement. Do not exceed the torque capacity appropriate for the fastener grade as specified by ASTM A574 guidelines.
