Insert SKD330 – high-performance screw-in insert for wood and engineered materials

The Insert SKD330 is a metal screw-in threaded insert with metric internal thread (M6, M8 or M10) and a patented speed-up external wood thread profile, engineered to create a strong, reusable and wear-resistant threaded fastening point directly in a pre-drilled hole in wood, MDF and similar board materials. Its beveled collar also acts as an automatic stop during installation, ensuring consistent mounting depth without the need for special tooling. 

Description

Product specifications for Insert SKD330

• Available bore sizes: M6, M8 and M10 metric internal threads suited to heavier duty wood and high-density panels.

• Material: steel with zinc plating for corrosion resistance in standard indoor industrial and commercial applications.

• External thread: patented multi-start coarse thread (speed-up outer thread) that reduces installation turns and provides tilt protection.

• Lead geometry: unthreaded lead section at the external end facilitates alignment and entry into the drilled hole, improving perpendicular installation and reducing assembly errors.

• Collar type: beveled sealing collar acts as stop and supports clean surface finish.

• Quality assurance: 100% functional inspection of critical dimensions such as length, internal thread and external thread for consistent performance.

• Primary substrates: solid wood, plywood, MDF and engineered boards; also suitable in certain plastics with correct geometry choice.

Product description and industrial benefits

The Insert SKD330 delivers a durable and reusable metric thread connection for industrial woodworking, bespoke joinery and B2B panel assembly. It supports repeated bolt insertions without degrading the wood fibres, improving product longevity in furniture and structural woodworking applications. Its high pull-out resistance and quick assembly profile make it ideal for professional production environments where reliability and throughput are essential.

Typical applications for Insert SKD330

Used in: solid timber constructions, medium-density boards, MDF and similar substrates where a strong threaded insert is required for mechanical fasteners in B2B manufacturing, cabinetry, industrial fixtures and custom joinery.
