S-99512A613 Length 5/8" Tapping Screws

Key Features & Benefits at a Glance

• Superior holding power in plastic materials thanks to the Tri-Lobe shank design that creates secure, vibration-resistant threads
• Enhanced corrosion resistance provided by the zinc-plated steel construction for extended service life in various environments
• High-torque installation capability with the T8 Torx drive, reducing cam-out and improving assembly efficiency
• Reduced risk of material splitting due to the thread-forming (TRS) design and blunt tip, ideal for delicate plastic components
• Consistent and reliable fastening ensured by the fully threaded, 28 TPI right-hand thread profile
• Broad compatibility and easy installation with the standard pan head profile and recommended 5/64" drill bit size
• Compliance with international environmental standards including RoHS 3 and REACH for responsible sourcing and use

Professional Applications & Engineering Value

These No. 2 x 5/8" thread forming screws are engineered specifically for plastic fastening applications, where traditional screws might cause cracking or stripping. The Tri-Lobe shank cross-section and thread forming (TRS) design displace material to create strong, permanent threads without pre-tapping, significantly reducing assembly time and improving joint integrity. Made from zinc-plated steel, they offer durability and corrosion resistance, making them suitable for electronics enclosures, automotive trim, and consumer appliances. The T8 Torx drive ensures high torque transfer during installation, minimizing driver slippage and head damage. This combination of features solves common industrial pain points like material failure, installation inefficiency, and long-term reliability in plastic components.

Specification Summary & Compliance

This screw features a No. 2 size with a 0.086" thread diameter and 28 TPI thread pitch, fully threaded to a 5/8" length. It has a standard pan head with T8 Torx drive, blunt tip, and right-hand thread direction. Manufactured from zinc-plated steel, it is designed for use with a 5/64" (0.0781") drill bit in plastic materials. The product complies with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, ensuring it meets stringent international standards for hazardous substance restrictions.
