Professional Applications & Engineering Value
This low truss head slotted screw combines the corrosion-resistant properties of 18-8 stainless steel with the mechanical advantages of a rounded truss profile to solve critical fastening challenges. The wide bearing surface of the truss head distributes clamping force effectively, preventing surface damage to softer materials while the passivated finish enhances corrosion protection in moist or chemical environments. The UNC coarse threading with Class 2A fit ensures rapid installation and reliable performance in vibration-prone applications such as machinery assembly, electrical enclosures, and automotive components. These fully threaded fasteners maintain consistent grip strength across their entire length, making them ideal for applications requiring uniform clamping pressure.
Specification Summary & Compliance
Manufactured to precise dimensional standards with Class 2A thread fit and UNC coarse threading (1/4"-20), this fastener delivers reliable performance in industrial settings. The screw meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance requirements, ensuring environmental safety and regulatory adherence. With a tensile strength rating of 80,000 psi and Rockwell B85 hardness, it maintains dimensional stability under load while the passivated surface treatment provides additional corrosion protection for extended service life.
