Professional Applications & Engineering Value

These 410 stainless steel tapping screws are engineered specifically for plastic assembly applications where material integrity and fastener reliability are critical. The DST thread forming technology eliminates the risk of plastic cracking or stress fractures common with traditional cutting screws, while the fully threaded design and 19 threads per inch configuration ensure maximum engagement strength in thermoplastic and thermoset materials. The Phillips pan head provides a low-profile, secure fastening solution that withstands vibration and thermal cycling in automotive components, electrical enclosures, consumer products, and industrial equipment. The combination of corrosion-resistant 410 stainless steel and precision thread forming makes these screws ideal for applications requiring repeated disassembly and reassembly without thread degradation.

Specification Summary & Compliance

This No. 6 x 3/4" tapping screw features a 0.138" thread diameter with right-hand threading and standard inch system measurements. The fastener meets industry standards for thread forming screws in plastic applications and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations. Manufacturing precision ensures consistent Class 2A thread fit and dimensional accuracy across all production batches, providing reliable performance in automated assembly environments.
