Value Collection -48549-7 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION -48549-7 is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, industrial equipment, and structural connections. The screw features a 3/4-16 UNF thread and measures 2-3/4 inches in length under the head. It is fully threaded and driven with a 5/8-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and moderate corrosion resistance in controlled environments. Machinists, millwrights, and maintenance technicians typically install this fastener where a recessed-drive, high-torque screw is required.

This cap screw suits a wide range of industrial, manufacturing, and mechanical maintenance applications. The 3/4-16 UNF fine thread pitch provides precise clamping force and strong thread engagement, making it appropriate for machine tool fixtures, hydraulic components, and equipment housings where vibration resistance and close-tolerance fits matter. The black oxide coating reduces surface reflectivity and provides light corrosion protection in dry or lightly oiled service environments.

Key Features

• 3/4-16 UNF fine thread for precise clamping and strong engagement
• 2-3/4 inch length under head — fully threaded along entire shank
• 5/8-inch hex drive socket head for high-torque installation
• Alloy steel construction for high tensile strength
• Black oxide finish for light corrosion resistance and low reflectivity
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as a standard replacement or maintenance fastener for applications requiring a 3/4-16 UNF hex socket cap screw conforming to ASME/ANSI B18.3 and ASTM A574 specifications.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated hex key or socket driver sized to 5/8 inch. Power down and de-energize all equipment before fastener installation or removal. Do not substitute an imperial hex key for metric sizes, as improper fit can round the socket. Follow applicable torque guidelines from the equipment manufacturer or relevant ASME standards for the fastener grade and size.
