Value Collection 307188BR Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 307188BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. This screw features a 3/4-10 UNC thread size and measures 5 inches in length under the head with partial threading along the shank. Drive engagement is achieved with a 9/16-inch hex key or Allen driver. Constructed from alloy steel with a black oxide finish, it delivers strong tensile performance and moderate corrosion resistance. Manufactured to ASTM A574 standards, it meets the mechanical requirements expected in demanding bolted joint applications. Weight is 0.05 pounds per fastener.

This screw is suited for use in general industrial machinery, equipment assembly, tooling fixtures, and fabrication environments where a recessed hex drive fastener is required. Partial threading allows the unthreaded shank to act as a guide or pivot in close-tolerance bored holes. Typical installers include machinists, millwrights, maintenance technicians, and fabricators working with medium to heavy steel components.

Key Features

• 3/4-10 UNC thread size for broad compatibility with standard inch-series tapped holes
• 5-inch length under head with partial threading for shank-guided fitment
• 9/16-inch hex socket drive for high-torque installation with standard Allen keys or socket drivers
• Alloy steel construction meets ASTM A574 mechanical strength requirements
• Black oxide finish provides moderate corrosion resistance and reduced light reflection

Compatibility

Designed as an OEM-style replacement or stock fastener for applications requiring a 3/4-10 UNC hex socket cap screw conforming to ASTM A574 standards.

Installation Notes

Installation is typically performed by machinists or maintenance technicians using a calibrated torque wrench with the appropriate 9/16-inch hex bit. Ensure the mating tapped hole is clean, free of debris, and properly sized for 3/4-10 UNC before installation. Apply thread lubricant or thread-locking compound as required by the assembly specification. De-energize and lock out all equipment before servicing fasteners on machinery per applicable OSHA lockout/tagout procedures.
