Professional Applications & Engineering Value

These No. 4-24 thread forming screws are specifically engineered for sheet metal applications where reliable fastening and corrosion resistance are critical. The 18-8 stainless steel construction provides excellent protection against rust and chemical exposure, making these tapping screws ideal for outdoor equipment, electronic enclosures, and HVAC systems. The thread forming design eliminates the need for separate tapping operations, reducing installation time and labor costs while creating strong, vibration-resistant connections. The slotted pan head offers compatibility with standard screwdrivers, while the fully threaded configuration ensures maximum engagement in thin materials. These sheet metal fasteners solve common assembly challenges by providing consistent performance in applications requiring 0.025" maximum drilling thickness with precise No. 44 drill bit compatibility.

Specification Summary & Compliance

This No. 4-24 x 3/8" tapping screw features a 0.112" thread diameter with 24 threads per inch in right-hand orientation. The screw meets standard thread forming specifications for Type A/AB tapping screws and is fully threaded for maximum holding power. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring safe use across various industrial applications. The dimensional accuracy ensures proper fit and performance in designated sheet metal thicknesses.
