**#8-32 x 1​/​2" UNC Grade 5 Titanium Socket Head Machine Screw – Polished Finish** This **#8-32 x 1​/​2" UNC socket head machine screw** is manufactured from **Grade 5 titanium (Ti-6Al-4V)**, a high-performance titanium alloy trusted across aerospace, marine, motorsports, and industrial applications. Known for its excellent combination of **strength, low weight, and corrosion resistance**, Grade 5 titanium is an ideal material for fastening applications where performance matters and traditional steel hardware may be too heavy or susceptible to corrosion. The **socket head design** provides secure tool engagement and a clean finished look, while the **polished finish** gives the fastener a professional appearance suitable for visible assemblies and premium builds. Manufactured to **ANSI B18.3 ​/​ ASME B18.3** standards with a tolerance of **+0 ​/​ -0.002 inch**, this screw is built for precision, consistency, and reliable fastening performance. Grade 5 titanium is especially well suited for use with **carbon fiber and composite materials**, where galvanic compatibility is important. It is also an excellent choice for **race cars, bicycles, motorcycles, sailboats, powerboats, engines, marine hardware, and custom fabrication projects** that require a lightweight, corrosion-resistant, and high-strength fastener. **Specifications:** * Size: **#8-32** * Length: **1​/​2 in** * Thread: **UNC** * Material: **Grade 5 Titanium (Ti-6Al-4V)** * Head Style: **Socket Head** * Finish: **Polished** * Standard: **ANSI B18.3 ​/​ ASME B18.3** * Tolerance: **+0 ​/​ -0.002 in** A lightweight, corrosion-resistant titanium machine screw designed for high-strength fastening in aerospace, marine, automotive, industrial, and composite applications.
