Product Description

The 1/4-20*1 screw is a 1/4-20 UNC bolt with a 1-inch length, designed as a versatile 1/4-20x1 fastener for industrial assembly applications. Featuring coarse UNC threading, it ensures robust mechanical fastening in automotive, construction, and machinery sectors. Operates reliably in temperatures ranging from -40°C to 120°C, compatible with standard torque tools, and offers corrosion resistance via zinc plating or stainless steel variants. Ideal for structural joints requiring moderate tensile strength, this fastener provides ease of installation but lacks compatibility with fine-threaded counterparts. Suitable for environments demanding vibration resistance and rapid assembly, though proper torque calibration is critical to prevent material stripping.
