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

Product Description

The VALUE COLLECTION -48549-3 is a hex socket cap screw engineered for high-strength fastening applications where a recessed drive and clean profile are required. Sized at 3/4-16 UNF with a 1-1/2 inch length under head, this fastener is fully threaded and driven with a 5/8 inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid corrosion resistance and surface hardness suitable for demanding mechanical and industrial installations. Machinists, maintenance technicians, and assembly professionals are the typical installers for this fastener type.

This cap screw is suited for general industrial, mechanical, and OEM assembly applications where a fine-thread 3/4-16 UNF pattern is specified. The fine thread pitch provides greater thread engagement per inch compared to coarse thread, making it a common choice in applications requiring tighter torque control or resistance to vibration loosening. The black oxide alloy steel construction is appropriate for use in enclosed or low-moisture environments. Sold individually with a minimum order quantity of 10 units.

Key Features

• 3/4-16 UNF fine thread for increased thread engagement and vibration resistance
• Fully threaded along the 1-1/2 inch length under head
• 5/8 inch hex socket drive for high-torque wrench or L-key installation
• Alloy steel construction for high tensile and shear strength
• Black oxide finish provides mild corrosion resistance and reduces surface glare
• Meets ASME/ANSI B18.3 and ASTM A574 fastener standards

Compatibility

Designed as an OEM-style hex socket cap screw for mechanical assemblies, fixtures, and equipment requiring a 3/4-16 UNF fully threaded fastener with a 5/8 inch hex drive.

Installation Notes

Installation is typically performed by machinists, millwrights, or maintenance technicians using a 5/8 inch hex key or socket driver. Always verify that the mating threaded hole or nut is clean, undamaged, and rated for the same thread specification before installation. Apply appropriate thread lubricant or anti-seize compound per the assembly specification. Power down or de-energize any equipment before performing fastener installation or replacement on live machinery.
