Value Collection 88547161 Hex Socket Cap Screw 3/4-10 Unc

Product Description

The VALUE COLLECTION 88547161 is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Sized at 3/4-10 UNC with a 3-inch length under the head, this screw is partially threaded and driven with a 5/8-inch hex key. The alloy steel construction provides excellent tensile strength and resistance to shear forces, while the black oxide coating adds moderate corrosion resistance and reduces light reflection in finished assemblies. Sold in a package of 3, this fastener is well suited for maintenance shops, OEM assembly lines, and field repair work. Machinists, millwrights, and maintenance technicians are the primary installers.

This screw is used in applications requiring a recessed-drive fastener with a full bearing-surface head — typical in machine frames, jigs, fixtures, pump housings, gearboxes, and heavy equipment assemblies. The partial thread is standard for larger-diameter cap screws at this length, allowing the smooth shank to act as a locating feature or bearing surface in bored holes. Suitable for both standard and metric-adjacent assemblies where 3/4-10 UNC thread engagement is specified by design or OEM documentation.

Key Features

• 3/4-10 UNC thread size for high-load fastening in structural and mechanical assemblies
• 3-inch length under head with partial threading — smooth shank aids alignment in close-tolerance bores
• 5/8-inch hex drive for use with standard hex keys and socket drivers
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and a low-reflectance surface
• Packaged in quantities of 3 to support small jobs and repair stock

Compatibility

Designed as a standard 3/4-10 UNC hex socket cap screw for use in any application requiring ASME B18.3 socket head cap screw geometry at this thread size and length.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician using a calibrated torque wrench and the appropriate 5/8-inch hex bit or L-key. Always degrease or lightly lubricate threads per the applicable fastener specification before torquing to the design value listed in your engineering documentation. Do not exceed the rated torque for alloy steel 3/4-10 fasteners as specified by your application or equipment OEM. Inspect threads in the mating component before installation to confirm they are clean, undamaged, and the correct thread class.
