• Efficient thread forming design creates strong, permanent threads in sheet metal without pre-tapping, reducing installation time
• Optimized for sheet metal applications with maximum 0.025" drilling thickness capability and No. 44 drill bit compatibility
• Secure Phillips drive engagement provides reliable torque transmission during installation with reduced cam-out risk
• Precise 82° countersink angle ensures flush mounting in standard countersunk holes for clean, professional finishes
• Full 3/4" threading delivers maximum grip length and holding power across the entire fastener
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe industrial use

Professional Applications & Engineering Value

These No. 4-24 TPI thread forming screws are specifically engineered for demanding sheet metal applications where reliable fastening is critical. The 18-8 Stainless Steel composition provides exceptional corrosion resistance, making these tapping screws ideal for outdoor equipment, HVAC systems, and electronic enclosures exposed to moisture or chemicals. The Type A thread forming design eliminates the need for separate tapping operations, as the screw creates its own perfectly matched threads in the material, preventing loosening from vibration and thermal cycling. The standard flat head profile with 82° countersink angle ensures smooth, flush installations that meet professional finish requirements while the Phillips drive offers familiar, efficient installation with standard tools.

Specification Summary & Compliance

This No. 4-24 x 3/4" tapping screw features precise 0.112" thread diameter with 24 threads per inch and fully threaded design for maximum engagement. The fastener maintains standard inch system measurements with Class 2A thread tolerances for consistent performance. Manufacturing complies with Type A tapping screw specifications for thread forming applications. The product is fully RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, meeting the latest environmental and safety regulations for industrial components.
