S-90123A429 Length 2 1/2" ASME B18.2.1 Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with 316 stainless steel construction, ideal for humid, marine, and chemical-exposed environments
• Enhanced driving efficiency with external hex head design providing maximum torque transfer and reduced cam-out
• Exceptional holding power through thread forming technology that compresses wood fibers without pre-drilling in many applications
• Optimized length and threading with 2-1/2" overall length and partial threading for controlled clamping force in wood connections
• Reliable dimensional consistency meeting ASME B18.2.1 specifications for precise fit and interchangeability
• Environmental compliance assurance with RoHS 3 and REACH regulations for safe use in regulated industries
• Versatile right-hand threading compatible with standard installation tools and procedures

Professional Applications & Engineering Value

These 316 stainless steel hex head wood screws deliver critical performance advantages in demanding wood construction and professional woodworking applications. The thread forming design creates permanent, vibration-resistant connections by displacing material rather than removing it, significantly increasing pull-out resistance in both softwoods and hardwoods. The external hex drive system ensures maximum torque application without stripping, while the partial threading provides controlled clamping force distribution. Particularly valuable in outdoor structures, marine environments, and industrial settings, these screws maintain integrity where moisture, chemicals, or temperature variations would compromise ordinary fasteners. The combination of corrosion-resistant 316 stainless steel and precision manufacturing according to ASME B18.2.1 standards makes them ideal for permanent installations requiring decades of reliable service.

Specification Summary & Compliance

This 1/2"-13 x 2-1/2" hex head wood screw features a 0.5" thread diameter with approximately 6 threads per inch and right-hand threading. The partially threaded design provides a minimum thread length of 1.667" with a pointed tip for easier starting. Manufactured to ASME B18.2.1 dimensional standards with a 3/4" hex head width and 0.344" head height. Fully compliant with RoHS 3 (2015/863/EU) restrictions on hazardous substances and REACH (EC 1907/2006) regulations for chemical safety, ensuring environmental responsibility and workplace safety.
