- DIN 7504 K compliance guarantees dimensional accuracy and performance reliability for European standards
Professional Applications & Engineering Value
These M4.2 x 32mm zinc-plated steel flanged tapping screws solve critical fastening challenges in metal fabrication and assembly operations. The self-drilling tip with No. 2 geometry penetrates steel and sheet metal up to 0.118" thick, eliminating separate drilling operations that increase production time and potential alignment errors. The thread-forming BSD design creates precise, high-strength threads in parent material without generating chips that could interfere with electrical components or moving parts. Combined with the external hex drive and integrated flange, these screws provide excellent clamp force distribution and resistance to vibration loosening in HVAC systems, electrical enclosures, and automotive assemblies where reliable metal-to-metal connections are essential.
Specification Summary & Compliance
This flanged hex head tapping screw features M4.2 diameter with 32mm length, fully threaded right-hand configuration, and meets DIN 7504 K standards (equivalent to ISO 15480) for dimensional precision and performance. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring suitability for regulated industries. Manufacturing follows thread-forming BSD specifications with Class 2A tolerance equivalent for consistent fit in steel and sheet metal applications.
