Professional Applications & Engineering Value
These 10-24 UNC rounded truss head screws deliver critical engineering advantages in demanding applications. The passivated 18-8 stainless steel provides excellent resistance to oxidation and chemical exposure, making them ideal for outdoor equipment, marine hardware, and food processing machinery where moisture is a concern. The wide truss head distributes clamping force over a larger area, preventing damage to soft materials and maintaining seal integrity in assembled components. With coarse threading and partial threading design, these screws offer superior pull-out resistance in wood, plastic, and sheet metal assemblies while allowing precise positioning. The combination of 70,000 psi tensile strength and Phillips No. 2 drive ensures reliable performance in vibration-prone environments, reducing maintenance needs and extending service life in industrial fastening applications.
Specification Summary & Compliance
This fastener features precise Class 2A thread fit with 10-24 UNC coarse threads and 2 3/4" length with partial threading. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and performance. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industries.
