Professional Applications & Engineering Value

These No. 8 x 3/8" tapping screws deliver exceptional engineering value in industrial fastening applications where material integrity and installation efficiency are critical. The 410 stainless steel composition provides excellent corrosion resistance while maintaining high strength, making these thread forming screws ideal for steel, stainless steel, and sheet metal assemblies. The BSD tapping screw design with fully threaded right-hand configuration and drilling tip eliminates the need for separate drilling operations, significantly reducing installation time and labor costs. This combination of material durability and installation efficiency makes them particularly valuable in manufacturing, construction, and metal fabrication where repetitive fastening operations demand reliability and speed.

Specification Summary & Compliance

These tapping screws feature precise No. 8 size with 0.164" thread diameter and 3/8" length, manufactured to exacting standards with 18 TPI precision threading. The thread forming design follows industry-standard BSD specifications for consistent performance. Compliance includes RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring environmental responsibility and workplace safety. The pan head with square drive (No. 2) provides secure installation while the drilling tip (No. 2 type) enables penetration of materials up to 0.035" maximum thickness without pre-drilling requirements.
