Value Collection 011009PR Hex Socket Cap Screw 1-72 Unf

Product Description

The VALUE COLLECTION 011009PR is a 1-72 UNF hex socket cap screw designed for precision fastening in tight, small-clearance applications. Manufactured from alloy steel with a black oxide coating, this screw delivers solid mechanical strength and modest corrosion resistance in a compact form factor. The 1/16-inch hex drive accepts a standard hex key, and the 1/8-inch length under head keeps the fastener profile low. It is fully threaded from tip to head, making it suitable for through-hole and thin-material installations. The black oxide finish reduces light reflection and provides a degree of surface protection in dry or lightly oiled environments.

This cap screw is used in instrument assembly, electronics enclosures, precision machinery, optical mounts, and other small-scale mechanical applications where a 1-72 UNF thread pattern is specified. The fine thread pitch provides strong thread engagement in thin materials and allows precise torque control during installation. Machinists, instrument technicians, and precision assembly professionals typically work with fasteners in this size range. The ASME/ANSI B18.3 and ASTM A574 standards governing this screw confirm it meets accepted dimensional and mechanical property requirements for socket cap screws.

Key Features

• 1-72 UNF fully threaded for maximum thread engagement in thin materials
• Alloy steel construction meets ASTM A574 mechanical property requirements
• Black oxide coating reduces surface reflection and offers light corrosion protection
• 1/16-inch hex drive compatible with standard hex keys and drivers
• 1/8-inch length under head suits shallow-clearance and thin-stock installations
• Conforms to ASME/ANSI B18.3 dimensional standards for socket cap screws

Compatibility

Designed as a standard 1-72 UNF hex socket cap screw for use in any application requiring ASME/ANSI B18.3-compliant socket head cap fasteners in this thread size and length.

Installation Notes

Installation requires a 1/16-inch hex key or ball-end driver sized for the socket. Always verify the mating thread is clean and free of debris before driving the screw. Do not exceed the torque capacity of the 1-72 thread form, as fine threads in small diameters are susceptible to galling and thread stripping. Alloy steel fasteners with black oxide finish should not be used in standing water or highly corrosive environments without additional protective treatment.
