Professional Applications & Engineering Value
These No. 4-20 thread forming screws are specifically engineered for plastic assembly applications where material integrity and long-term performance are critical. The 18-8 stainless steel construction provides excellent corrosion resistance, while the tri-lobe shank design displaces plastic material to create strong, permanent threads without tapping. This eliminates the need for inserts and reduces assembly steps. The Phillips pan head offers reliable drive engagement, and the blunt tip prevents plastic splitting during installation. These TRS screws are ideal for electronics enclosures, automotive plastic components, and consumer products where vibration resistance and environmental compliance are essential requirements.
Specification Summary & Compliance
These tapping screws feature a No. 4-20 thread size with 20 threads per inch and 1" length, manufactured with precision thread forming technology for plastic applications. The screws comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring they meet current industry standards for hazardous substance restrictions. Designed for use with No. 37 drill bits (0.104" diameter), these fully threaded screws provide consistent performance in various plastic fastening scenarios.
