Value Collection -48549-8 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION -48549-8 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural components. It features a 3/4-16 UNF thread size with a 3-inch length under the head and is partially threaded for controlled engagement. The drive is a 5/8-inch hex socket, requiring a standard hex key or Allen socket driver. Manufactured from alloy steel and finished with a black oxide coating, this fastener delivers solid tensile strength and modest corrosion resistance in dry or lightly oiled service environments. Installation to ASME/ANSI B18.3 and ASTM A574 standards makes it a recognized specification fastener for trade and industrial use.

This screw is suited for use in machinery maintenance, fabrication shops, industrial equipment assembly, and general mechanical repair where a 3/4-16 UNF partially threaded socket cap screw is specified. The black oxide finish reduces light reflection and provides a degree of surface protection. Machinists, millwrights, and maintenance technicians are the primary installers. It is sold in a minimum order quantity of 5 pieces, with each package containing 1 piece.

Compatibility

Designed as an OEM-style replacement or specification fastener for applications requiring a 3/4-16 UNF hex socket cap screw per ASME/ANSI B18.3 and ASTM A574 standards.

Installation Notes

Installation should be performed by a qualified machinist, millwright, or maintenance technician familiar with fastener torque and thread engagement requirements. Always ensure the mating threaded hole is clean and free of debris before installation. Consult applicable engineering specifications or torque charts for the correct tightening value, as none are provided with this part. Do not use impact tools without verifying torque control capability.
