Overview
The 316SS 1/2-13 X 1 3/4 hex cap screw is a high-performance fastener engineered for applications requiring maximum corrosion resistance. These screws are manufactured from 316 stainless steel, an austenitic alloy that outperforms standard 304 stainless steel in aggressive chemical and marine environments.
Key Features
- Superior corrosion resistance compared to 304 or 18-8 stainless steel
- Molybdenum and nickel alloying for harsh environment performance
- Hex head design for easy installation with standard wrenches
- ASME B18.2.1 compliant dimensions and specifications
- Suitable for marine, chemical processing, food equipment, and coastal applications
Technical Specifications
Meets ASME B18.2.1 standards for hex head cap screws. The 1/2-13 UNC thread specification provides standard coarse-thread compatibility across industrial applications. Material composition includes molybdenum (2–3%) and nickel (10–14%), distinguishing 316 from lower-grade austenitic alloys.
Typical Applications
- Marine and offshore equipment requiring salt-spray resistance
- Chemical and food processing machinery
- Coastal infrastructure and exposed fastening
- Industrial equipment in corrosive atmospheres
- Pharmaceutical and water treatment systems
Compatibility & Replacements
Compatible With
- 1/2-13 UNC threaded holes and assemblies
- Standard hex wrenches and socket tools
- Any fastening application accepting 1/2-13 cap screws
Replaces / Drop-In Replacement For
This screw is a direct replacement for any standard 316 stainless steel 1/2-13 X 1 3/4 hex cap screw meeting ASME B18.2.1 specifications. Verify exact dimensional and material requirements with your equipment manufacturer before ordering.
Works With
- 316L stainless steel washers and nuts (matching corrosion resistance)
- Any 1/2-13 tapped hole or nut assembly
- Marine-grade and industrial fastening systems
