Value Collection 581234PR Hex Socket Cap Screw 6-40 Unf

Product Description

The VALUE COLLECTION 581234PR is a fully threaded hex socket cap screw designed for precision fastening applications requiring a compact drive profile. Sized to 6-40 UNF thread specification with a 1-inch length under head, this fastener is driven with a 7/64-inch hex key. Constructed from alloy steel with a black oxide finish, it delivers solid tensile strength and moderate corrosion resistance in a controlled-environment setting. Meets ASME/ANSI B18.3 and ASTM A574 standards. Maintenance technicians, machinists, and mechanical assemblers working with fine-thread applications will find this screw suited to tight-tolerance assemblies.

This cap screw is used in mechanical assemblies, machine components, fixtures, and equipment panels where a recessed hex drive is preferred over an external head. The 6-40 UNF fine thread pitch provides strong clamping force in thin-material applications. The black oxide finish reduces light reflection and provides light surface protection. Typical installations include precision instruments, actuators, HVAC equipment panels, and general mechanical assemblies requiring a low-profile, flush-capable fastener.

Key Features

• 6-40 UNF fully threaded profile for fine-pitch clamping in thin or precision materials
• 1-inch length under head accommodates moderate-depth fastening applications
• 7/64-inch hex socket drive for use with standard hex keys or Allen drivers
• Alloy steel construction meets ASTM A574 mechanical requirements
• Black oxide finish provides light corrosion resistance and low-glare appearance
• Conforms to ASME/ANSI B18.3 dimensional standards

Compatibility

Designed as an OEM-style replacement or stock fastener for mechanical assemblies requiring a 6-40 UNF hex socket cap screw with a 1-inch length under head and 7/64-inch drive. Minimum order quantity is 100 pieces per order.

Installation Notes

Installation is performed by machinists, maintenance technicians, or mechanical assemblers using a 7/64-inch hex key or compatible Allen driver. Ensure mating threads are clean and free of debris before installation. De-energize and lock out any equipment before fastener replacement or service. Do not exceed the design torque rating for the thread size and material grade of the mating component.
