[100 PKG] Socket Head Cap Screws Fine Thread Alloy Steel Thermal Black Oxide 1-72 X 3/8

Introducing our high-strength Socket Head Cap Screw, engineered for demanding assemblies that require precise threading, strong clamping, and a discreet finish. This Fine Thread Alloy Steel screw uses a thermal black oxide finish for durability and reduced glare in challenging environments. With a 1-72 thread and a 3/8 inch length, it delivers reliable performance in tight spaces.

Key features

• Head type: Socket head cap screw
• Material: Alloy steel for strength and durability
• Finish: Thermal black oxide for corrosion resistance and a low-reflective surface
• Thread: Fine thread 1-72 UNC (per inch) for precise engagement
• Size: Length 3/8 inch
• Drive: Internal hex socket for secure drive and easy installation

Benefits

Designed to withstand high-stress applications, these screws provide consistent torque transfer and resistance to loosening when paired with the appropriate mating parts. The fine thread enables precise adjustment and holding power in tight tolerances, while the alloy steel body ensures high tensile strength.

Ideal applications

Perfect for precision machinery, electronics assemblies, automotive fixtures, and other engineering projects where space is limited and reliability is critical.

Installation tips

• Choose the correct hex driver to avoid galling or stripping the socket
• Use a light threading lubricant as recommended by your engineering guidelines
• Torque to your components specification to ensure optimal clamping force
