Overview

NSi Industries JTEKD21SS is a 12 x 1-1/2 inch hex washer head drill tip screw with a 5/16-inch drill tip and #3 point, manufactured from 410 stainless steel. The drill tip design eliminates pre-drilling, reducing installation time by up to 40% compared to conventional screws in metal applications. The hex washer head provides a flush, low-profile finish with increased bearing surface for enhanced pull-out resistance in soft materials like wood or plastic. Ideal for harsh environments, the 410 stainless steel offers corrosion resistance in marine, automotive, and industrial settings where exposure to moisture, salt, or chemicals is common. The #3 point geometry ensures clean penetration into steel up to 1/8-inch thick without wandering. Common applications include HVAC ductwork, electrical enclosures, roofing, and machinery assembly where secure, vibration-resistant fastening is required. The screw meets industrial standards for tensile strength and shear resistance, ensuring reliable performance in structural and non-structural connections.
