Professional Applications & Engineering Value

These No. 4-24 thread forming tapping screws deliver exceptional engineering value for sheet metal applications where vibration resistance and permanent fastening are critical. The nickel-plated steel construction provides excellent corrosion protection while maintaining high tensile strength. The A/AB thread forming design eliminates the need for tapping operations, creating strong internal threads through material displacement rather than cutting. This prevents metal chips from contaminating sensitive assemblies while providing superior resistance to loosening under vibration. The standard 82° flat head profile ensures flush mounting in pre-drilled holes using a No. 44 drill bit (0.086" diameter), making these Phillips flat head screws ideal for electronics enclosures, HVAC systems, and automotive components where clean finishes and reliable performance are essential.

Specification Summary & Compliance

These thread forming tapping screws feature precision No. 4-24 threads with Class 2A tolerance, right-hand thread direction, and 0.112" thread diameter. The fully threaded design with pointed tip and round shank cross-section ensures maximum engagement in materials up to 0.025" thickness. Manufactured to A/AB tapping screw standards with Phillips No. 1 drive and standard flat head profile. Fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial use worldwide.
