S-91735A327 6-32 x 1 3/4" ASME B18.6.3 Stainless Steel Pan Head Phillips Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance in harsh environments thanks to 316 stainless steel construction and passivated finish
• Exceptional mechanical strength with 80,000 psi tensile strength and Rockwell B85 hardness for reliable load-bearing performance
• Optimized drive engagement with Phillips No. 2 drive style ensuring efficient installation and reduced cam-out risk
• Consistent thread performance through fully threaded UNC coarse threads with Class 2A fit for secure fastening
• Enhanced durability from rounded pan head design that resists stripping and distributes clamping force effectively
• Regulatory compliance assurance meeting ASME B18.6.3 standards and environmental regulations including RoHS 3 and REACH
• Versatile 1-3/4" length providing ample threading engagement for various material thicknesses in industrial assemblies

Professional Applications & Engineering Value

These 316 stainless steel rounded head screws deliver critical corrosion protection where exposure to chemicals, moisture, or marine environments would compromise ordinary fasteners. The passivated finish creates an additional protective oxide layer, significantly extending service life in demanding applications from food processing equipment to marine hardware. The combination of fully threaded UNC coarse threads and Class 2A thread fit ensures rapid installation with consistent clamping force, while the Phillips drive system provides familiar, efficient torque transfer. With 80,000 psi tensile strength and Rockwell B85 hardness, these industrial fasteners maintain structural integrity under vibration and dynamic loads, making them ideal for machinery, electrical enclosures, and structural assemblies where reliability is non-negotiable.

Specification Summary & Compliance

This 6-32 UNC screw features precision Class 2A thread fit tolerances and complies with ASME B18.6.3 manufacturing specifications. The product meets RoHS 3 (2015/863/EU) compliance for hazardous substance restrictions and REACH (EC 1907/2006) regulations for chemical safety. Manufacturing adheres to standardized dimensions including 0.138" thread diameter, coarse thread spacing, and consistent 1-3/4" length for reliable interchangeability in industrial applications.
