Key Features & Benefits at a Glance
- Superior corrosion resistance with 18-8 Stainless Steel construction, ensuring long-term reliability in harsh industrial environments.
- Enhanced holding power through thread forming technology, creating strong, permanent threads in sheet metal without pre-tapped holes.
- Wide truss head design provides excellent load distribution and prevents pull-through in thin sheet metal applications.
- Efficient installation with No. 1 Phillips drive, offering secure tool engagement and reduced cam-out during driving.
- Full threading along the 1" length delivers maximum grip and uniform stress distribution for secure fastening.
- Compatible with No. 44 drill bit (0.086" diameter), simplifying hole preparation and ensuring precise fit in 0.025" maximum thickness materials.
- Compliance with RoHS 3 and REACH regulations guarantees safe, environmentally responsible use in industrial settings.
Professional Applications & Engineering Value
This No. 4-24 thread forming tapping screw is specifically engineered for sheet metal applications, where traditional fasteners often struggle with material fatigue and stripping. The 18-8 Stainless Steel composition provides excellent resistance to oxidation and chemical exposure, making it ideal for outdoor equipment, HVAC systems, and electronic enclosures. Its thread forming design displaces material rather than cutting it, resulting in stronger thread engagement and reduced risk of metal shavings contaminating sensitive assemblies. The wide truss head distributes clamping force over a larger area, preventing deformation in thin-gauge metals and maintaining structural integrity under vibration. With a No. 1 Phillips drive and fully threaded shank, it ensures quick installation and reliable performance in high-volume manufacturing environments.
Specification Summary & Compliance
This screw features a No. 4-24 thread (0.112" diameter, 24 TPI) with Class 2A tolerance for consistent fit. The thread forming (Type A/AB) tapping method and pointed tip facilitate easy penetration into pre-drilled holes (recommended No. 44 drill bit, 0.086" diameter). It is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) regulations, ensuring adherence to industrial safety and environmental standards.
