S-92186A738 1/2"-13 x 7" ASME B18.2.1 Super-Corrosion-Resistant 316 Stainless Steel Hex Head Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial environments and outdoor applications
• Exceptional mechanical strength with 70,000 psi tensile strength and Rockwell B70 hardness for reliable performance under heavy loads
• Precise thread engagement with Class 2A thread fit ensuring consistent assembly and reduced risk of cross-threading
• Optimized load distribution through partial threading design that concentrates strength where needed most
• Easy installation and removal with external hex drive and 3/4" head width providing excellent tool access and torque application
• Industry-standard compatibility with UNC coarse threads that resist loosening in high-vibration applications
• Regulatory compliance assurance meeting ASME B18.2.1 specifications while being RoHS 3 and REACH compliant

Professional Applications & Engineering Value

This 316 stainless steel hex head screw delivers exceptional engineering value across demanding industrial applications where corrosion resistance and structural integrity are paramount. The 1/2"-13 UNC coarse threading provides superior holding power in soft materials and resists vibration-induced loosening, making it ideal for construction equipment, marine hardware, and chemical processing installations. The partially threaded design concentrates tensile strength in the shank while allowing for precise clamping force distribution. With external hex drive and substantial head dimensions, installation torque is efficiently transferred without stripping, reducing assembly time and maintenance costs. The combination of 70,000 psi tensile strength and premium 316 stainless steel material ensures long-term reliability in corrosive environments where ordinary fasteners would rapidly deteriorate.

Specification Summary & Compliance

This 7" hex head screw features precise Class 2A thread fit with 1/2"-13 UNC coarse threading and 1 1/4" minimum thread length. Manufactured to ASME B18.2.1 specifications with complete compliance to RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. The inch system measurement ensures compatibility with North American industrial standards and replacement applications.
