Professional Applications & Engineering Value
This 316 stainless steel slotted pan head screw delivers exceptional performance in corrosive and high-stress environments where ordinary fasteners fail. The combination of 80,000 psi tensile strength and passivated finish creates a durable industrial fastener that withstands chemical exposure, moisture, and temperature variations. The UNC coarse threads with Class 2A fit ensure quick assembly and reliable holding power in materials where fine threads might strip. Ideal for marine equipment, chemical processing machinery, food processing applications, and outdoor installations, this fully threaded screw provides consistent clamping force across its entire 3/4" length, making it a versatile solution for engineers requiring corrosion resistant screws with proven mechanical properties.
Specification Summary & Compliance
This fastener maintains precise Class 2A thread fit tolerances per UNC standards with 4-40 thread size and right-hand threading. Manufacturing complies with ASME B18.6.3 specifications for dimensional accuracy and mechanical properties. The product meets RoHS 3 (2015/863/EU) compliance for restricted substances and REACH (EC 1907/2006) regulations for chemical management, ensuring global environmental standard adherence.
