Key Features & Benefits at a Glance
- Exceptional tensile strength of 120,000 psi ensures reliable performance in demanding applications, reducing the risk of fastener failure.
- Superior corrosion resistance from the Black-Oxide finish on Alloy Steel extends service life in harsh industrial environments.
- Precise Class 3A thread fit guarantees tight, secure connections with minimal play, enhancing assembly integrity.
- Flanged design eliminates the need for separate washers, speeding up installation and providing a larger bearing surface.
- Coarse UNC threads allow for quick engagement and reduced cross-threading, ideal for high-vibration settings.
- Hex drive compatibility with a 1/8" drive enables easy installation and removal using standard tools, improving workflow efficiency.
- Full threading along the 1" length offers maximum grip and adjustability in various material thicknesses.
Professional Applications & Engineering Value
This 10-24 UNC Class 3A Rounded Head Screw is engineered to address common industrial challenges such as vibration loosening and corrosion-induced degradation. Constructed from Black-Oxide Alloy Steel with a hardness of Rockwell C32, it withstands high-stress conditions in machinery, automotive, and construction sectors. The flanged button head distributes clamping force evenly, preventing surface damage, while the coarse thread ensures rapid assembly in coarse-grained materials. Its fully threaded design and right-hand thread provide consistent holding power, making it a go-to for heavy-duty fastening where reliability and compliance with environmental standards are critical.
Specification Summary & Compliance
This screw adheres to UNC thread standards with a Class 3A fit for precise dimensional accuracy, featuring a 10-24 thread size, 1" length, and flange diameter of 0.406". It is manufactured to meet RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring it is free from hazardous substances and suitable for global industrial use.
