S-90610A719 Length 1 1/4" Wood Screws

Key Features & Benefits at a Glance

• Enhanced corrosion resistance with Black-Oxide steel coating for longer service life in various environments
• Superior torque transmission and reduced cam-out thanks to the square drive design for reliable installation
• Stronger, vibration-resistant threads in wood and hardwood due to thread forming technology that displaces material
• Precise, flush installation with a standard flat head profile and 82° countersink angle for a clean finish
• Optimized wood penetration and reduced splitting with a pointed tip and recommended drill bit sizes (3/32" for hardwood, 5/64" for softwood)
• Secure, stable fastening with a partially threaded shank that minimizes material stress
• Compliance with international safety standards including RoHS 3 and REACH for safe industrial use

Professional Applications & Engineering Value

These No. 8 wood screws are engineered to solve common fastening challenges in woodworking and construction. The Black-Oxide steel material provides a durable barrier against rust, extending the screw's lifespan in both indoor and protected outdoor applications. The thread forming design is particularly valuable as it creates stronger, more permanent threads in wood and hardwood by compressing the material rather than cutting it, which reduces the risk of stripping and provides superior pull-out resistance. The combination of a square drive and flat head ensures high torque application without slippage, while the partially threaded shank and pointed tip facilitate easier starting and prevent wood splitting, making them ideal for furniture assembly, cabinetry, and structural wood connections where reliability is critical.

Specification Summary & Compliance

This screw features a No. 8 size with a 0.164" thread diameter and 15 threads per inch in a right-hand direction. The length is 1-1/4" with a minimum thread length of 0.83", a round shank cross-section, and a standard flat head profile (0.332" diameter, 0.1" height). It is manufactured to be RoHS 3 (2015/863/EU) Compliant and REACH (EC 1907/2006) Compliant, ensuring adherence to strict environmental and safety regulations for hazardous substances.
