• High-strength performance delivering 80,000 psi tensile strength and Rockwell B85 hardness for reliable, durable fastening
• Precise thread engagement with Class 2A UNC coarse threads ensuring consistent fit and reduced cross-threading risks
• Full threading along the 1" length provides maximum grip and adjustment flexibility in various material thicknesses
• Easy installation and removal using standard slotted drive tools, simplifying maintenance and assembly processes
• Compliance with environmental regulations including RoHS 3 and REACH, supporting sustainable and safe manufacturing practices

Professional Applications & Engineering Value

This 1/4-20 UNC low truss head slotted screw is engineered to address common industrial challenges such as vibration loosening, corrosion-induced failure, and assembly inefficiency. The 18-8 stainless steel material combined with a passivated finish offers exceptional resistance to rust and chemicals, making it suitable for outdoor equipment, marine applications, and food processing machinery where moisture exposure is frequent. The low, wide truss head distributes clamping force over a larger area, minimizing the risk of surface damage on softer materials like plastics or composites. With its coarse UNC threads and Class 2A thread fit, it ensures quick installation and reliable holding power in wood, metal, and plastic assemblies, reducing labor time and enhancing structural integrity in automotive, electronics, and construction projects.

Specification Summary & Compliance

This screw features a 1/4"-20 UNC coarse thread with Class 2A thread fit for standard dimensional accuracy and ease of assembly. It is fully threaded along a 1" length with a right-hand thread direction and slotted drive style. Manufactured from 18-8 stainless steel with a passivated finish, it meets RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) compliance, ensuring adherence to environmental and safety regulations without hazardous substances.
