Value Collection -48549-5 Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION -48549-5 is a fully threaded hex socket cap screw designed for high-strength fastening applications. It features a 3/4-16 UNF thread size and a 2-inch length under head, making it suited for precision-fit assemblies where fine thread engagement and clamping force are critical. The screw is manufactured from alloy steel with a black oxide finish, providing corrosion resistance in controlled environments. Drive size is 5/8 inch hex. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards and is installed by maintenance technicians, millwrights, and mechanical contractors in industrial and commercial settings.

This cap screw is used in mechanical assemblies, equipment mounting, and structural fastening where a fine-thread alloy steel fastener is required. The 3/4-16 UNF thread pitch provides greater thread engagement per inch compared to coarse-thread equivalents, making it a common choice for applications requiring high torque retention and vibration resistance. It is appropriate for use in machinery, fabricated steel structures, and equipment frames across industrial and commercial environments.

Key Features

• 3/4-16 UNF fine thread for high torque retention and vibration resistance
• 2-inch length under head for consistent clamping depth
• Fully threaded shank provides maximum thread engagement
• Alloy steel construction rated to ASTM A574 for high-strength performance
• Black oxide coating provides mild corrosion resistance in dry or lightly oiled environments
• 5/8-inch hex drive compatible with standard hex keys and socket drivers
• Meets ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or standard-service hex socket cap screw for mechanical assemblies requiring a 3/4-16 UNF fully threaded fastener in alloy steel.

Installation Notes

Installation should be performed by qualified mechanics or millwrights using a calibrated torque wrench and a properly sized 5/8-inch hex key or socket driver. De-energize and lock out all equipment before fastener service per applicable OSHA lockout/tagout procedures. Black oxide finish is not a heavy-duty corrosion barrier; apply thread lubricant or anti-seize compound as appropriate for the service environment. Verify thread engagement depth and mating thread condition before final torque.
