Overview

The NSi Industries JSRM85 Stainless Steel Machine Screw is a precision-engineered fastener designed for industrial and mechanical assemblies requiring corrosion-resistant, durable fastening. Manufactured from 18-8 grade stainless steel, this screw combines high tensile strength with excellent resistance to rust, oxidation, and wear, making it ideal for harsh environments such as marine, chemical processing, and outdoor infrastructure applications. The 1/4-20 thread size and 1-1/4 inch length provide a secure fit for medium-duty fastening needs, while the round head and slotted drive type ensure easy installation using standard flat-head screwdrivers. With a 100-piece bulk packaging, the JSRM85 is optimized for OEMs, maintenance teams, and industrial contractors who require reliable, consistent fasteners in bulk quantities. This machine screw meets UNSPSC code 31161504 and is proudly made in the USA, ensuring traceable quality and compliance with domestic manufacturing standards. Typical applications include machinery assembly, equipment mounting, panel fastening, and general-purpose mechanical joining where a clean, low-profile head is preferred. The 18-8 grade stainless steel offers a balance of cost efficiency and performance, delivering corrosion resistance superior to carbon steel fasteners without the premium cost of 316 stainless. Its slotted drive provides positive engagement and prevents cam-out, ensuring reliable torque transfer during installation. The screw’s dimensions are precisely machined to ANSI B18.6.3 standards, guaranteeing compatibility with standard 1/4-20 tapped holes and clearance holes. For projects requiring durable, long-lasting fasteners in corrosive or high-moisture environments, the JSRM85 delivers consistent performance with minimal maintenance.
