Value Collection 015487BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 015487BR is a partially threaded hex socket cap screw intended for high-strength bolted assemblies in industrial, mechanical, and structural applications. It carries a 3/4-10 UNC thread size with a 6-inch length under head, and is driven by a 5/8-inch hex (Allen) key. Manufactured from alloy steel and finished with a black oxide coating, it provides increased hardness and moderate corrosion resistance compared to standard mild steel fasteners. This screw meets ASME/ANSI B18.3, ASTM A574, and IFI 124 standards, making it suitable for demanding load-bearing connections. Machinists, millwrights, and maintenance technicians are the typical installers.

This fastener is used wherever a recessed-drive, high-torque cap screw is required in tight or countersunk clearances. Common applications include machine frames, jigs and fixtures, equipment mounting, and general industrial assembly where a flush or low-profile head is preferred over a hex bolt. The partial threading allows the unthreaded shank to act as a shoulder or locating feature in close-tolerance bores, which is useful in precision machinery and tooling setups.

Key Features

• 3/4-10 UNC thread for high load capacity and wide tool availability
• 6-inch length under head with partial threading for shank engagement in close-tolerance bores
• 5/8-inch hex socket drive for high-torque installation with standard Allen keys or hex bits
• Alloy steel construction meets ASTM A574 high-strength socket screw requirements
• Black oxide finish provides mild corrosion resistance and reduces light reflection in optical or precision assemblies
• Conforms to ASME/ANSI B18.3 and IFI 124 dimensional standards for consistent fitment

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for use in any application requiring a 3/4-10 UNC partially threaded socket head cap screw in alloy steel.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a 5/8-inch hex key or driven hex bit at the appropriate torque for the joint material and grade. Always de-energize, depressurize, or lock out equipment before accessing fastener locations on operating machinery. Do not use impact drivers at full power on fine-clearance holes without confirming thread engagement to avoid cross-threading. Verify mating thread condition and bore depth before seating to full length under head.
