Product Description

The 1/2-13x2.5 Bolts are precision-engineered fasteners with a 1/2-13 UNC threaded rod design, featuring a 2.5-inch hex head for robust mechanical assembly. These high-strength 2.5-inch hex head screws are crafted from hardened steel, ensuring durability in demanding environments. Designed for industrial applications such as heavy machinery, construction, and automotive systems, they provide reliable fastening under extreme temperatures (-40°C to 120°C) and resist corrosion in humid or chemically exposed settings. The 1/2-13 UNC threads ensure compatibility with standardized nuts and fixtures, offering optimal torque resistance and vibration-proof performance. While lacking integrated electronics or communication interfaces, their primary advantage lies in exceptional tensile strength and ease of installation using standard tools. Potential limitations include manual alignment requirements for threaded engagement. Ideal for structural applications requiring rugged, reusable fasteners.
