Value Collection 015449BR Hex Socket Cap Screw 5/8-18 Unf

Product Description

The VALUE COLLECTION 015449BR is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and structural connections. Manufactured from alloy steel with a black oxide finish, it provides reliable clamping force and moderate corrosion resistance in controlled environments. The 5/8-18 UNF thread designation indicates a fine-thread profile, which delivers greater thread engagement and holding strength compared to coarse-thread equivalents. Drive size is 1/2 inch hex socket. Length under head is 2-1/2 inches. This fastener is well-suited for machinists, maintenance technicians, and industrial assemblers working with precision-threaded connections.

This cap screw is appropriate for use in industrial machinery, automotive assemblies, hydraulic equipment, and general fabrication where fine-thread fasteners are specified. The alloy steel construction handles high tensile loads, making it a dependable choice for bolted joints that require controlled preload. Partial threading allows the unthreaded shank to provide shear resistance in applications where alignment and lateral loads are a concern. Sold individually, with a minimum order quantity of 10 units.

Key Features

Compatibility

Designed as a standard-dimension replacement or service fastener for any application specifying a 5/8-18 UNF partially threaded hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 1/2 inch hex key or socket driver. Always verify that the mating threaded hole or nut is clean, free of debris, and properly sized for 5/8-18 UNF threads before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. Follow applicable torque values specified in the equipment service documentation or engineering drawings, as no torque value was provided with this product listing.
