S-90485A110 Length 1/4" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 18-8 stainless steel construction for long-lasting performance in demanding environments
• Excellent holding power in plastic materials due to the Tri-Lobe shank cross section that prevents loosening and back-out
• Efficient thread forming design creates strong, permanent threads in plastic without pre-tapping requirements
• Reliable drive engagement with Phillips No. 1 drive style for secure installation and reduced cam-out risk
• Flush mounting capability with standard 82° flat head profile that sits neatly in countersunk applications
• Full thread coverage along the entire 1/4" length ensures maximum grip and distribution of clamping force
• Regulatory compliance with RoHS 3 and REACH standards for environmentally responsible manufacturing

Professional Applications & Engineering Value

This TRS Type A tapping screw delivers exceptional engineering value for plastic assembly applications where vibration resistance and material integrity are critical. The thread forming design with Tri-Lobe shank cross section creates a secure, permanent fit in plastic substrates without creating chips or debris that could compromise electronic components. The 18-8 stainless steel construction provides excellent corrosion resistance, making these plastic fasteners ideal for outdoor equipment, automotive trim, electronic enclosures, and consumer products exposed to moisture or chemicals. The combination of 0.086" thread diameter and 28 TPI fine threading ensures minimal stress concentration in plastic materials while maintaining high pull-out strength. The Phillips flat head configuration with standard profile allows for clean, flush installations in pre-drilled holes using a No. 48 drill bit, streamlining your assembly process while maintaining aesthetic appeal.
