Value Collection 48548 Hex Socket Cap Screw 5/8-11 Unc

Product Description

The VALUE COLLECTION 48548 is a partially threaded hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. It features a 5/8-11 UNC thread size and measures 7.5 inches in length under the head. The screw is driven with a 1/2-inch hex key. Constructed from alloy steel with a black oxide finish, this fastener delivers solid tensile strength and moderate corrosion resistance. It conforms to ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for applications where dimensional and mechanical consistency is required. Sold in a pack of 5.

This cap screw is suited for use in heavy machinery, fixtures, tooling plates, and general industrial equipment where a flush or recessed drive head is preferred over a hex bolt. The 5/8-11 UNC coarse thread pattern is well-matched to through-holes in steel, cast iron, and similar ferrous materials. The partial threading allows for greater shank grip length in thicker material stacks. Machinists, millwrights, maintenance technicians, and industrial contractors typically specify this fastener in shop and field assembly work.

Key Features

• 5/8-11 UNC coarse thread for use in ferrous and structural materials
• 7.5-inch length under head accommodates thick material stacks
• Partial thread design maximizes shank engagement in deep applications
• Alloy steel construction rated to ASTM A574 for high tensile strength
• Black oxide finish provides mild corrosion resistance and reduces light glare
• 1/2-inch hex drive compatible with standard allen keys and hex bit sockets

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw for use in 5/8-11 UNC tapped holes in industrial machinery, fixtures, and structural assemblies.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2-inch hex key or socket bit. Ensure the tapped hole is clean and free of debris before driving. Do not over-drive; consult the equipment manufacturer's torque specifications for the specific joint material and grade requirement. Apply thread lubricant or anti-seize compound as directed by the equipment service documentation.
