Overview

NSI Industries TP401SRC Tamper-Resist One-Way Machine Screws are precision-engineered fasteners designed for secure, tamper-evident installations in industrial, commercial, and OEM applications. These #6-32 stainless steel screws measure 3/4" in length with a round head and #6 Phillips drive, providing a clean, low-profile finish while resisting unauthorized removal. Manufactured from Type 18-8 stainless steel, they deliver superior corrosion resistance and durability in harsh environments, including outdoor, marine, and chemical exposure scenarios. The one-way design ensures screws can only be driven in—not out—making them ideal for security-sensitive applications such as electrical enclosures, control panels, and access panels where tampering must be prevented. Each package includes 100 screws, optimized for bulk purchasing and high-volume assembly operations. Compatible with standard #6 drivers and wrenches, these screws are designed for use in pre-drilled or pre-tapped holes, eliminating the need for additional threading operations. The built-in washer provides a flush, secure fit against mating surfaces, reducing the risk of loosening under vibration. NSI Industries, a trusted U.S.-based manufacturer, ensures consistent quality and reliability for critical fastening applications. These screws meet UNSPSC code 31161504 and are suitable for UL-listed enclosures requiring Type 4X ratings. Whether used in telecommunications, industrial machinery, or security systems, TP401SRC screws provide a cost-effective solution for tamper-resistant fastening without compromising installation efficiency.
