Professional Applications & Engineering Value
These No. 10-18 thread forming tapping screws deliver exceptional value in steel and sheet metal fabrication by addressing critical installation challenges. The 410 stainless steel composition provides reliable corrosion resistance while the BSD thread forming design creates precise, secure threads without generating chips or debris. The integrated No. 2 drill tip with 5/16" length enables direct penetration through materials up to 0.175" thick, eliminating separate drilling operations and reducing assembly time. The fully threaded 1-1/4" length ensures maximum engagement strength, while the oval head with Phillips drive offers both aesthetic appeal and practical installation efficiency for HVAC, electrical enclosures, and metal building components.
Specification Summary & Compliance
These tapping screws feature a No. 10-18 thread with 0.19" diameter and 18 threads per inch, manufactured to BSD standards for thread forming applications. The oval head design includes a standard profile with 0.362" diameter and 82° countersink angle. All specifications comply with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use in industrial and commercial applications worldwide.
