S-91555A127 Length 2 3/4" Wood Screws

Key Features & Benefits at a Glance

• Superior corrosion resistance with black-oxide steel coating, extending screw lifespan in humid or demanding woodworking environments
• Enhanced material compatibility through thread forming technology, creating stronger, permanent threads in fiberboard and particleboard without pre-tapping
• Optimized load distribution with pan head design and 0.322" head diameter, preventing surface damage while maintaining secure fastening
• Reduced splitting risk with partial threading design, allowing unthreaded shank to act as a pivot point in brittle composite materials
• Streamlined installation using standard No. 2 Phillips drive and 5/64" drill bit, compatible with common workshop equipment
• Reliable grip strength from 11 threads per inch configuration, ensuring maximum holding power in wood composite applications
• Precision alignment with pointed tip design, enabling accurate screw placement and easier penetration into dense materials

Professional Applications & Engineering Value

These black-oxide steel wood screws are engineered specifically for the unique challenges of fiberboard and particleboard applications, where traditional fasteners often cause material splitting or strip-out. The thread forming technology eliminates the need for pre-tapped holes by displacing material to create permanent, high-strength threads that actually improve the structural integrity of wood composites. The partial threading design prevents the common issue of material separation in layered boards, while the corrosion-resistant black-oxide finish ensures long-term performance in environments where moisture or temperature variations would degrade standard fasteners. The combination of No. 2 Phillips drive and precise 5/64" pilot hole specification delivers consistent installation performance for production environments, reducing tool wear and installation time in commercial woodworking and construction applications.

Specification Summary & Compliance

These No. 8 x 2-3/4" wood screws feature inch system measurements with 0.164" thread diameter and 11 threads per inch configuration. The fasteners maintain standard industrial tolerances for wood screw applications, with right-hand threading and partial threading extending 1.842" from the pointed tip. The pan head style provides a standard rounded profile with 0.322" diameter and 0.115" height. Manufacturing complies with industry standards for thread forming screws in wood composite materials, with material specifications meeting general industrial requirements for steel fasteners in construction applications.
