Ingco ST5.0x100mm Yellow Zinc Chipboard Screws (HWBS5010011) – High-Performance Heat-Treated Countersunk Wood Fasteners

Achieve flush, heavy-duty fastening in thick timber, particleboard, and composite woods with the professional-grade engineering of the INGCO HWBS5010011 Chipboard Screw. Featuring a robust ST5.0 gauge thread diameter and an extra-long 100mm length profile, these premium wood fasteners are specifically designed to pull thick timber joints tightly together and handle deep structural connections. They provide carpentry contractors, cabinet makers, and DIY woodworkers with a reliable, high-torque fastening solution for heavy woodworking and framing.

Forged from premium steel, these screws undergo an advanced heat-treatment process to drastically increase their structural hardness and shear resistance, preventing the heads from snapping under high torque. The countersunk (CSK) head design is paired with a specialized Pozi drive recess, which minimizes driver slip (cam-out) and ensures clean, flat surface integration. Finished with a yellow zinc plating, these screws are highly guarded against rust and oxidation while blending seamlessly with natural wood tones.

Key Technical Features:

• Model: HWBS5010011

• Screw Dimensions: ST5.0 Thread Gauge Diameter x 100mm Total Length – Engineered for extra-deep, high-strength timber embedding

• Drive Type: Precision Pozi Drive – Offers superior grip and high-torque transfer compared to standard Phillips drives

• Head Style: Countersunk (CSK) Head – Sinks flush into workpieces to deliver a smooth, clean surface finish without snagging

• Metallurgical Treatment: Advanced Heat Treatment – Enhances core structural strength and flexibility to resist snapping under stress

• Surface Coating: Premium Yellow Zinc Plated Finish – Provides robust defense against moisture, rust, and industrial corrosion

• Thread Pattern: Deep, sharp wood-cutting threads that bite quickly into materials to reduce wood splitting and lower driving friction

• Application Range: Highly optimized for fastening medium-density fiberboard (MDF), softwoods, hardwoods, chipboards, plywood sheets, cabinet frames, heavy structural timber framing, and outdoor wooden structures
