Value Collection 581734BR Hex Socket Cap Screw 3/4-16 Unf

Product Description

The VALUE COLLECTION 581734BR is a hex socket cap screw designed for high-strength fastening applications in mechanical assemblies, tooling, and industrial equipment. It features a 3/4-16 UNF thread size with a 3-1/4 inch length under head and accepts a 5/8 inch hex drive. Constructed from alloy steel with a black oxide finish, this screw delivers strong tensile performance and basic corrosion resistance in controlled environments. It is partially threaded, which helps maintain clamping force across joined materials. This fastener meets ASME/ANSI B18.3 and ASTM A574 standards, making it suitable for demanding bolted joints where dimensional and strength requirements must be verified.

This socket cap screw is used in a wide range of industrial and mechanical applications including machine frames, fixtures, hydraulic components, and close-tolerance assemblies. It is well suited for situations where a low-profile head and internal hex drive are required for access-restricted fastening. Maintenance technicians, machinists, millwrights, and mechanical contractors commonly install this type of fastener. Sold individually per package with a minimum order quantity of 10 units.

Key Features

• 3/4-16 UNF thread for fine-pitch clamping in high-load applications
• 3-1/4 inch length under head with partial threading for reliable joint clamping
• 5/8 inch hex socket drive for use with standard hex keys and drivers
• Alloy steel construction meets ASTM A574 high-strength fastener requirements
• Black oxide finish provides mild corrosion resistance in dry or lightly oiled environments
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

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

Installation Notes

Install using a calibrated hex key or socket drive tool sized to 5/8 inch. De-energize and lock out all equipment before fastener removal or replacement in live assemblies. Apply thread lubricant or fastener adhesive per the equipment manufacturer's recommendations. Verify mating thread condition and hole depth before installation to avoid cross-threading or insufficient engagement.
