Key Features & Benefits at a Glance
- Superior corrosion resistance with zinc-plated steel construction, extending service life in demanding industrial environments
- Exceptional holding power from 60,000 psi tensile strength and Rockwell B70 hardness, preventing fastener failure under heavy loads
- Effortless installation with Phillips No. 3 drive design, reducing assembly time and tool slippage risks
- Reliable thread engagement through UNC coarse threading and Class 2A fit, ensuring consistent performance in vibration-prone applications
- Maximum fastening coverage with fully threaded design, providing superior grip across the entire screw length
- Reduced head protrusion with rounded pan head profile, creating cleaner installations in confined spaces
- Regulatory compliance assurance meeting ASME B18.6.3, RoHS 3, and REACH standards for global industrial acceptance
Professional Applications & Engineering Value
Engineered for industrial fastening solutions, these zinc-plated steel screws deliver critical performance where vibration resistance and environmental durability are paramount. The UNC coarse thread configuration prevents cross-threading during high-speed assembly while maintaining secure connections in machinery, equipment frames, and structural components. The rounded pan head design distributes clamping force efficiently, reducing surface damage while the Phillips drive enables rapid installation with standard tools. With full threading along the entire 3/4" length, these Class 2A thread fit fasteners provide maximum thread engagement in both thick and thin materials, solving common challenges of stripped threads and loosening under dynamic loads.
Specification Summary & Compliance
This 1/4"-20 x 3/4" screw maintains precise Class 2A thread fit tolerances with UNC coarse thread spacing (20 threads per inch) and right-hand threading. Manufactured to ASME B18.6.3 specifications with Rockwell B70 hardness and 60,000 psi tensile strength. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for safe use across global industrial markets.
