Overview

NSI Industries TP320SPC is a precision-engineered 1/4-20 x 1" machine screw designed for demanding industrial applications requiring secure, corrosion-resistant fastening. Manufactured from 18-8 stainless steel, this screw delivers exceptional resistance to rust, oxidation, and harsh environmental conditions, making it ideal for marine, automotive, aerospace, and heavy industrial environments. The pan head design ensures a low-profile, flush finish that minimizes surface disruption while providing optimal load distribution across the fastened material. The spanner drive type (#14 driver size) offers superior torque transfer and tamper resistance, reducing slippage and cam-out during installation. This combination of features makes the TP320SPC particularly well-suited for sheet metal fabrication, HVAC systems, electrical enclosures, and structural assemblies where reliability and long-term performance are critical. The 1/4-20 thread pitch provides strong mechanical engagement in metal substrates, while the 1" length offers sufficient thread engagement for most sheet metal and thin-wall applications. NSI Industries, a trusted name in industrial fasteners, ensures consistent thread quality and dimensional accuracy, meeting or exceeding industry standards for stainless steel fasteners. Whether used in original equipment manufacturing or field repairs, the TP320SPC delivers predictable clamping force and vibration resistance, reducing the risk of loosening over time. Packaged for industrial use, this screw is available as a standalone component for bulk applications or integrated into assembly kits where precise, repeatable fastening is required.
