S-99512A510 Length 1/2" Tapping Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with zinc-plated steel construction, ensuring long-lasting performance in various industrial environments
• Enhanced torque transfer and reduced cam-out thanks to the Torx Plus IP30 drive, allowing for higher tightening forces and improved assembly efficiency
• Exceptional holding power in plastic materials due to the tri-lobe shank design, which minimizes rotation and provides secure, vibration-resistant fastening
• Reliable thread forming without pre-drilling in many plastic applications, simplifying installation and reducing labor time with the TRS thread forming type
• Consistent fastening performance with fully threaded 1/4" diameter and 10 TPI, ensuring uniform grip and load distribution
• Broad compatibility and safety compliance meeting RoHS 3 and REACH regulations, making them suitable for global markets and environmentally conscious projects
• Easy identification and handling with a standard pan head and blunt tip, facilitating quick assembly and reducing damage to materials

Professional Applications & Engineering Value

These 1/4" zinc-plated steel tapping screws are specifically engineered for plastic applications, where traditional fasteners may strip or loosen under stress. The TRS thread forming design and tri-lobe shank create strong, permanent threads in plastic substrates, eliminating the need for inserts and reducing assembly costs. With a Torx Plus IP30 drive, they enable high-torque installation without slippage, minimizing tool wear and ensuring precise fastening in automated or manual settings. Ideal for industries like automotive, electronics, and consumer goods, these screws provide durable, vibration-resistant connections that maintain integrity in dynamic environments, while the zinc-plated finish offers added protection against corrosion, extending service life in humid or outdoor conditions.

Specification Summary & Compliance

This product features a 1/4" thread diameter with approximately 10 threads per inch and a 1/2" length, designed for right-hand threading and fully threaded application. It complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) standards, ensuring adherence to environmental and safety regulations. The screw utilizes a thread forming tapping method (Type TRS) and is intended for use in plastics, with recommended drill bit size A (0.234" diameter) for optimal performance. Manufactured to precise dimensional tolerances, it supports reliable fastening in industrial settings.
