S-91555A123 Length 1 1/2" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating for extended service life in various environmental conditions
• Enhanced material engagement through thread forming technology that creates strong, permanent threads in fiberboard and particleboard
• Reduced splitting and cracking with partial threading design that minimizes stress on engineered wood materials
• Quick and precise installation with pointed tip and Phillips No. 2 drive for efficient driving using standard 5/64" drill bits
• Optimal load distribution thanks to pan head design with 0.322" diameter that provides excellent bearing surface
• Secure fastening performance with 11 TPI thread pattern ensuring maximum holding power in wood composite materials
• Consistent driving experience with rounded head profile that prevents cam-out and ensures reliable installation

Professional Applications & Engineering Value

These No. 8 wood screws are specifically engineered to address the unique challenges of fastening in fiberboard and particleboard applications. The thread forming technology eliminates the need for pre-tapped holes while creating strong, permanent threads that won't strip or loosen over time. The black-oxide steel construction provides essential corrosion protection for interior applications where moisture or humidity may be present. The partially threaded design concentrates the holding power where it's needed most while reducing the risk of material splitting in engineered wood products. The combination of Phillips drive and pointed tip ensures quick, accurate installation in production environments, making these screws ideal for furniture manufacturing, cabinet making, and construction applications where reliable fastening in composite wood materials is critical.

Specification Summary & Compliance
