Professional Applications & Engineering Value

Engineered for industrial applications requiring reliable fastening under substantial loads, these 10-24 UNC zinc-plated steel screws deliver exceptional performance in machinery assembly, structural frameworks, and heavy equipment. The coarse thread design provides superior holding power in softer materials and faster installation times, while the rounded head profile distributes clamping force evenly to prevent surface damage. The zinc-plated steel construction offers critical corrosion protection in environments exposed to moisture and chemicals, significantly extending service intervals. With partial threading optimizing stress distribution, these screws prevent joint loosening in high-vibration applications, making them ideal for automotive, construction, and manufacturing sectors where durability and precision are paramount.

Specification Summary & Compliance

This 4" length screw features precise Class 2A thread fit with UNC coarse threading (10-24 size) ensuring dimensional accuracy and reliable engagement. Manufactured to meet ASME B18.6.3 specifications for dimensional consistency and performance standards. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming absence of restricted hazardous substances. The inch system measurements (0.19" thread diameter, 0.359" head diameter) maintain compatibility with standard industrial components and tooling.
