Product Description

The 1/4-20 x 7/8 fastener is a precision 1/4-20 UNC screw designed for robust mechanical fastening in industrial applications. This 7/8 inch machine bolt features a unified national coarse (UNC) thread pattern, ensuring secure connections in machinery, automotive assemblies, and structural frameworks. Crafted from corrosion-resistant steel with optional zinc or galvanized coatings, it operates effectively within a temperature range of -40°C to 120°C. The bolt supports tensile loads up to 4,500 psi and tolerates torque levels up to 12 ft-lbs, making it ideal for high-stress environments. Its standardized dimensions ensure compatibility with most 1/4-20 threaded components, though the 7/8 inch length may limit use in compact spaces. Requires no external power, communication interfaces, or modules. Primary industries include manufacturing, construction, and electronics assembly. Key advantages: durability, precision threading, and adaptability; potential drawback: limited customization for non-standard applications. No integrated battery, display, or sensing components.
