Value Collection -48549-10 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION -48549-10 is a partially threaded hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, fixtures, and industrial equipment. Sized at 3/4-16 UNF with a 4-1/2 inch length under head, it accepts a 5/8 inch hex drive and meets ASME/ANSI B18.3 and ASTM A574 standards. Constructed from alloy steel with a black oxide finish, it delivers corrosion resistance and a clean, low-reflectance appearance suited to precision and structural installations alike. Machinists, millwrights, and maintenance mechanics rely on this fastener for secure, high-load connections.

This screw is suited for use in industrial machinery, tooling fixtures, structural assemblies, and equipment maintenance applications requiring a fine-thread, large-diameter cap screw. The 3/4-16 UNF thread pitch provides greater thread engagement and resistance to loosening under vibration compared to coarse-thread equivalents, making it a common choice in demanding mechanical environments.

Key Features

• 3/4-16 UNF fine thread for strong clamping force and vibration resistance
• 4-1/2 inch length under head accommodates thick material stacks
• 5/8 inch hex socket drive for high-torque installation with standard Allen keys or hex bits
• Alloy steel construction meets ASTM A574 strength requirements
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Partially threaded shank allows for precise load-bearing shank fit in through-hole applications

Compatibility

Designed as an OEM-style replacement or standard hex socket cap screw for industrial and mechanical assemblies requiring a 3/4-16 UNF partially threaded fastener.

Installation Notes

Installation should be performed by a qualified mechanic or millwright using a calibrated torque wrench and the appropriate 5/8 inch hex key or drive bit. Ensure mating threads are clean and free of debris before installation. De-energize and lock out all relevant equipment per OSHA lockout/tagout procedures before fastener replacement in powered machinery. Do not use impact drivers without a torque-limiting adapter to avoid thread damage or fastener failure.
