S-90184A115 Length 1" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for harsh industrial and marine environments
• Efficient thread forming design creates strong, permanent threads in sheet metal up to 0.025" thickness without pre-tapping
• Maximum torque transfer through Phillips No. 1 drive, reducing cam-out and tool slippage during installation
• Full threading with pointed tip ensures quick starting and secure fastening throughout the entire screw length
• Standard pan head profile provides a low-profile finish with good bearing surface for consistent clamping force
• Environmental compliance meets RoHS 3 and REACH standards for safe use in regulated industries
• Precise fitment with No. 44 drill bit compatibility ensures proper hole sizing for optimal thread engagement

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers exceptional performance in demanding sheet metal applications where corrosion resistance is critical. The thread forming design (Type A/AB) eliminates the need for separate tapping operations, creating strong, vibration-resistant threads that won't strip or loosen under stress. The fully threaded construction with pointed tip ensures immediate engagement and consistent holding power across the entire fastener length. Particularly valuable in industrial equipment, marine components, and outdoor enclosures, this screw maintains integrity in corrosive environments while providing reliable, permanent fastening in materials up to 0.025" thickness. The Phillips drive offers familiar installation with good torque transmission for production efficiency.

Specification Summary & Compliance

This No. 4-24 x 1" tapping screw features right-hand threads with approximately 24 threads per inch and Class 2A thread tolerances for consistent fit. Manufactured to Type A/AB thread forming standards with a round shank cross-section and standard pan head profile (0.219" diameter, 0.08" height). The screw is designed for use with No. 44 drill bit (0.086" diameter) and complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations for industrial applications.
