The VALUE COLLECTION 307180BR is a partially threaded hex socket cap screw designed for high-strength bolted connections in mechanical, structural, and industrial applications. It features a 3/4-10 UNC thread size and a 3-1/4 inch length under the head, providing substantial grip for thick or layered assemblies. The 9/16 inch hex drive socket head accepts a standard hex key or Allen driver. Manufactured from alloy steel and finished with a black oxide coating, this fastener meets ASTM A574 specifications, which define mechanical requirements for socket head cap screws used in demanding load-bearing installations.
This fastener is suited for general industrial and manufacturing applications where high tensile strength and a low-profile socket head are required. It is commonly used in machine frames, jigs, fixtures, and structural assemblies. The partial threading leaves a shank section near the head, which is preferred in applications requiring a tight shear fit through mating components. Maintenance mechanics, machinists, and millwrights typically install this type of fastener in both OEM and MRO settings.
Designed as a standard ASTM A574 socket head cap screw for use in any 3/4-10 UNC tapped hole requiring a 3-1/4 inch partially threaded fastener with a hex socket drive.
Installation should be performed by a qualified mechanic or machinist using a properly sized 9/16 inch hex key or T-handle driver. Ensure the mating tapped hole is clean and free of debris before threading to prevent galling or cross-threading. Apply appropriate thread lubricant or threadlocker per the assembly specification. Torque to the value specified by the equipment manufacturer or applicable industry standard for 3/4-10 alloy steel fasteners.
