Value Collection 581744BR Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION 581744BR is a hex socket cap screw designed for high-strength fastening applications in industrial, mechanical, and structural assemblies. Made from alloy steel with a black oxide finish, this screw measures 5.5 inches in length under the head and features a 3/4-16 UNF thread with partial threading. Drive size is 5/8 inch hex (Allen). The black oxide coating provides moderate corrosion resistance and reduces light glare on the fastener surface. Manufactured to ASME/ANSI B18.3 and ASTM A574 standards, this cap screw is suited for applications requiring a clean countersunk profile and reliable clamping force.

This hex socket cap screw is used across a wide range of industrial and mechanical applications, including equipment assembly, tooling fixtures, hydraulic component mounting, and heavy machinery. The 3/4-16 UNF fine thread pitch provides greater thread engagement and superior clamping force compared to coarse-thread equivalents, making it well suited for vibration-prone assemblies or installations requiring precise torque control. It is commonly installed by machinists, millwrights, and maintenance technicians working on industrial and commercial equipment.

Key Features

• 3/4-16 UNF fine thread for higher clamping strength and vibration resistance
• 5.5 inches length under head with partial threading
• 5/8 inch hex drive for use with standard Allen wrenches or hex bit sockets
• Alloy steel construction meets ASTM A574 high-strength requirements
• Black oxide finish for moderate corrosion protection and low-glare surface
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as a standard ASME/ANSI B18.3 hex socket cap screw suitable for any application requiring a 3/4-16 UNF partially threaded fastener with a 5/8 inch hex drive.

Installation Notes

Installation is performed using a 5/8 inch hex key or Allen-type socket driver. Always clean and inspect mating threads before installation to ensure proper engagement. Power down and de-energize any equipment before accessing fastener locations on live machinery. Follow applicable equipment manufacturer torque guidelines and relevant ASME or OSHA standards for fastener installation in your application.
