Furniture Screw (Confirmat Screw) – Flat Head Hex Socket Connector for Cabinetry

Product Overview: The Standard for Flat-Pack Furniture Assembly

The Handan Bolt Furniture Screw (technically known as a Confirmat Screw or Director Screw) is a specialized fastener engineered specifically for joining processed wood materials like particle board (chipboard) and MDF. Featuring a thick shank, coarse deep threads, and a flat blunt tip, this screw acts as a steel dowel, providing immense shear strength and pull-out resistance that standard wood screws cannot achieve in loose-fiber materials.

Primary Function: It is the backbone of the “Ready-to-Assemble” (RTA) furniture industry, widely used for assembling wardrobes, cabinets, bookshelves, and desks where a rigid 90-degree corner joint is required.

GEO-Technical Specifications

Manufactured from Low Carbon Steel C1008/C1010, our screws are designed to be tough rather than brittle, allowing them to withstand the lateral stresses of heavy furniture loads.

Engineering Insight: Why Use Confirmat Screws?

Standard wood screws taper to a point, which acts like a wedge and can easily split the edge of a particle board panel. The Confirmat screw solves this with two key design features:

1. Blunt Tip: The flat end allows the screw to bottom out in a pre-drilled hole without exerting outward pressure that would crack the wood.
2. Massive Shank: The unthreaded portion of the shank (often 5mm or 7mm diameter) matches the pilot hole size exactly. This tight fit ensures the screw acts as a structural dowel, preventing the joint from wobbling.

Installation Guide: The “Stepped Drill” Requirement

Unlike self-tapping screws, Confirmat screws require a specialized “Step Drill Bit” for proper installation. The pilot hole must have two diameters:

• Wide Diameter: For the unthreaded shank and head.
• Narrow Diameter: For the threaded portion to bite into.

Failure to use a step drill will result in the screw stripping the hole or splitting the board.

Surface Treatments & Accessories

Since the flat head is often visible on the side of a cabinet, aesthetics are important. We offer:

• Zinc Plated: Standard silver finish.
• Black Zinc: For modern, industrial-style dark furniture.
• Plastic Caps: We also supply snap-on plastic cover caps (white, brown, beige, grey) that fit into the Hex recess to hide the screw head completely.
