Professional Applications & Engineering Value
Engineered for industrial applications requiring durable and corrosion-resistant fastening, these rounded truss head Phillips screws address common challenges in machinery, electronics, and outdoor equipment assembly. The passivated 18-8 stainless steel material prevents rust and chemical degradation, extending service life in humid or corrosive settings. The wide truss head distributes clamping force over a larger area, minimizing the risk of surface damage on softer materials. Combined with UNC coarse threads and Class 2A thread fit, these screws provide reliable, vibration-resistant connections that maintain integrity under stress, making them ideal for heavy-duty fasteners in automotive, construction, and marine industries.
Specification Summary & Compliance
This screw features a 1/4"-20 UNC coarse thread with Class 2A thread fit for precise dimensional accuracy and ease of assembly. Manufactured in compliance with ASME B18.6.3 specifications, it ensures consistent quality and performance. The product is also RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, confirming adherence to environmental and safety regulations for industrial use.
