Product Description

The 1/4-20x2-3/4 fasteners are 1/4-20 threaded bolts with a 2.75in length, designed for secure assembly in mechanical, automotive, and industrial equipment. These 1/4-20 2.75 machine screws feature a unified coarse thread (20 threads per inch) for compatibility with standard nuts and threaded holes, providing robust tensile strength up to 1,500 psi. Made from grade-2 steel with zinc plating, they resist corrosion in environments ranging from -40°C to 120°C. Ideal for mounting brackets, motor housings, or electrical enclosures, their 2.75in shank enables mid-depth penetration in materials up to 0.5in thick. Advantages include vibration resistance and tool compatibility with hex keys or screwdrivers. Limitations include requiring pre-drilled pilot holes for hard surfaces and unsuitability for high-shear applications.
