Overview

The NSi Industries JSRM31P is a precision stainless steel machine screw engineered for industrial fastening applications requiring corrosion resistance and long-term reliability. This 1/4-20 x 3/4" fastener is manufactured from 18-8 grade stainless steel, offering superior resistance to rust, oxidation, and chemical exposure compared to standard carbon steel fasteners. The round head with Phillips drive type enables efficient installation using standard hand or power tools, while the unified thread design ensures consistent engagement in metal, plastic, or composite substrates. Each 100-piece pack provides a cost-effective solution for OEMs, maintenance teams, and fabrication shops where bulk fasteners are required. Ideal for use in food processing equipment, marine hardware, chemical processing plants, and outdoor structural assemblies, the JSRM31P meets ASTM A193 and A276 standards for stainless steel fasteners. The 18-8 designation indicates 18% chromium and 8% nickel content, providing balanced strength and corrosion resistance for most industrial environments.
  • 1/4-20 thread size with 3/4" length for secure fastening in metal and composite materials
  • 18-8 stainless steel composition (18% chromium, 8% nickel) for corrosion and oxidation resistance
  • Round head with Phillips drive type for compatibility with standard installation tools
  • Packaged 100 per box for bulk industrial and maintenance applications
  • Meets ASTM A193 and A276 standards for stainless steel fasteners
