Key Features & Benefits at a Glance
- Superior thread retention with tri-lobe shank design that creates vibration-resistant threads in plastic materials
- Excellent corrosion resistance provided by 18-8 stainless steel construction for long-lasting performance in demanding environments
- Efficient installation with Phillips No. 3 drive that ensures reliable torque transfer and reduces cam-out
- Secure fastening surface from the pan head design that distributes clamping force evenly across plastic components
- Reliable thread forming capability that eliminates the need for tapping operations in plastic applications
- Full threading along the 3/4" length provides maximum engagement strength in plastic assemblies
- Environmental compliance with RoHS 3 and REACH regulations for safe use in regulated industries
Professional Applications & Engineering Value
These 1/4"-10 thread forming TRS screws are specifically engineered to address common challenges in plastic fastening applications where vibration resistance and material integrity are critical. The tri-lobe shank design of these 18-8 stainless steel tapping screws displaces plastic material during installation, creating permanent, high-strength threads that won't loosen under dynamic loads. The Phillips drive configuration combined with the pan head style ensures consistent installation torque and reliable seating without damaging delicate plastic components. This makes them ideal for industrial applications in electronics enclosures, automotive plastic assemblies, and consumer products where vibration-resistant fastening is essential for product longevity and performance.
Specification Summary & Compliance
These screws feature a 1/4" thread diameter with 10 threads per inch and 3/4" length with fully threaded design. The thread forming TRS type utilizes a tri-lobe cross-section for optimal performance in plastic materials. Manufactured from 18-8 stainless steel with Phillips No. 3 drive and pan head configuration. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for use in restricted substance-sensitive applications.
