S-90184A120 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Exceptional corrosion resistance with 316 stainless steel construction, ideal for harsh environments and outdoor applications
• Superior material integrity maintains strength and prevents thread stripping in sheet metal up to 0.025" thickness
• Efficient thread forming design creates strong, permanent threads without chips, reducing installation time and improving joint reliability
• Optimized drive engagement with Phillips No. 2 drive prevents cam-out and provides secure torque transmission
• Full threading along entire length ensures maximum grip and uniform stress distribution across the fastened materials
• Standard pan head profile offers low-profile installation with good bearing surface for secure fastening
• Regulatory compliance assurance meets RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

This 316 stainless steel tapping screw delivers critical performance advantages in demanding sheet metal applications where corrosion resistance and joint integrity are paramount. The thread forming technology eliminates the need for pre-tapped holes while creating stronger, more reliable threads that resist vibration loosening. The fully threaded design provides consistent clamping force across the entire fastener length, preventing material distortion in thin-gauge metals. Engineered with 18 TPI fine threading and Phillips pan head configuration, this fastener ensures precise installation in HVAC systems, electronic enclosures, and industrial equipment where exposure to moisture, chemicals, or salt spray would compromise ordinary fasteners. The compatibility with No. 32 drill bits simplifies installation planning while the A/AB screw type guarantees standardized performance across your manufacturing operations.

Specification Summary & Compliance

This inch-system fastener features precision right-hand threads with standard thread forming (Type A/AB) specifications. The No. 6 screw size (0.138" thread diameter) with 1/4" length and 18 TPI thread pitch ensures dimensional accuracy for consistent performance. Manufacturing complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming the absence of restricted substances. The pointed tip facilitates easy starting while the round shank cross-section maintains structural integrity during installation into pre-drilled holes sized for No. 32 drill bits (0.116" diameter).
