Product Overview

Particleboard is a lower-density engineered material made from compressed wood particles. Chipboard Screws use a coarse, deep thread, relatively slim core and sharp starting point to improve engagement. Particleboard, MDF, softwood, plywood and hardwood do not behave identically, so pilot-hole strategy, screw diameter, point geometry and installation conditions should match the actual board.

Full-thread screws provide engagement along most of the usable length and suit many thin-panel and hardware applications. Partial-thread screws leave a smooth or reduced-thread section beneath the head; when the threaded portion engages the base material and the upper component can move along that section, the joint may draw together. Thread length remains an important purchasing variable and does not by itself guarantee a gap-free joint.

Buyers should specify diameter, length, full or partial thread, head, drive, material, finish, board type and thickness, edge distance, pilot-hole condition, application and quantity. Drawings or samples help VALTOR verify custom thread, point, countersinking and packaging requirements.

Technical Specifications

Alternative Name

Particle Board Screws / Particleboard Screws

Traditional Reference

DIN 7505 style where applicable; a legacy market dimensional reference, not universal for every modern design

Head Options

Primary countersunk flat head; raised countersunk, pan-type or custom heads where specified

Drive Options

Pozidriv / Type Z, Phillips / PH and Torx-type / 6-lobe; PZ and PH require different compatible drivers

Common Diameter

3.0 / 3.5 / 4.0 / 4.5 / 5.0 / 6.0 mm; 2.5 mm for selected requirements

Commercial Length

Approximately 10–200 mm depending on diameter, thread configuration, material and product design

Thread / Point

Coarse chipboard thread, full or partial thread, sharp starting point

Materials / Finishes

304 / 316 stainless steel, carbon steel; natural or passivated stainless, zinc-plated or specified finish

Typical Materials Fastened

Particleboard, chipboard, MDF, softwood, engineered wood and suitable furniture panels

Key Dimensions

Diameter d, pitch P, length L, head diameter and height, drive size, core diameter, thread length and point length

Thread Geometry, Point Design & Board Selection

Coarse Thread & Slim Core

Deep thread contact supports engagement in lower-density board; holding performance still depends on board density, thickness, diameter, engagement, edge distance and installation.

Sharp Point

A sharp point assists starting, but pilot holes may be needed near edges, in brittle or dense material, with larger stainless screws or where alignment is critical.

Board Selection

Particleboard benefits from coarse engagement; MDF requires attention to edge distance and pilot holes; softwood may be suitable, while hardwood should be evaluated for pre-drilling and correct geometry.

Full Thread

Continuous engagement for thin panels, brackets, hardware and applications requiring thread along most of the screw length.

Partial Thread

A smooth section beneath the head can allow an upper component to move while the threaded section engages the base material.

Optional Features

Cutting ribs, milling ribs, serrations and specialized points are optional product-specific designs—not universal DIN 7505 requirements.

Material, Size & Thread Options

✓304 Stainless Steel — For furniture, equipment wood components and suitable corrosion-resistant indoor or exterior assemblies.

✓316 Stainless Steel — For increased corrosion resistance in humid, coastal and more corrosive service conditions.

✓Carbon Steel — A common commercial choice for furniture, cabinetry and panel assembly with suitable surface treatment.

✓Commercial Range — Common diameters 3.0–6.0 mm and lengths approximately 10–200 mm; not every diameter is offered in every length.

✓Thread Options — Full or partial thread, with short/medium 10–60 mm, medium/long 70–120 mm and extended 140–200 mm configurations where technically suitable.

Drive, Head & OEM Manufacturing

✓Drive Selection — PZ, PH and Torx-type 6-lobe options. Pozidriv and Phillips are distinct recesses and require matching tools.

✓Head & Point — Countersunk flat head is primary; custom raised countersunk, pan-type, cutting-rib or specialized point designs are available by specification.

✓OEM Information — Provide diameter, length, thread length, drive, head, material, finish, board, thickness, application, quantity and drawing or sample.

✓Packaging — Small boxes, inner bags, export cartons, bulk packs, pallets and authorized customer or private labels.

Board Fit, Installation & Quality Control

✓Dimensional & Drive Inspection — Verify diameter, length, pitch, thread length, head, point, recess depth, symmetry, tool engagement and burr control.

✓Thread & Point Inspection — Check thread continuity, core diameter, point transition, concentricity, sharpness and damage.

✓Installation Samples — Representative particleboard, MDF, softwood or customer panels may be checked for starting, seating, splitting and engagement.

✓Testing & Documentation — Pullout testing only follows an agreed procedure. MTCs, dimensional reports, inspection reports and third-party support are available by order.

Frequently Asked Questions

What is the difference between a Chipboard Screw and a regular Wood Screw?

Chipboard Screws generally use a coarse thread, slim core and sharp point optimized for particleboard, MDF and similar materials. Traditional Wood Screws may use different shank, thread and head geometry.

Should I use Full Thread or Partial Thread Chipboard Screws?

Full thread engages along most of the length. Partial thread can help draw an upper component toward the base when its smooth section passes through the upper part and its thread engages the lower material.

What is the difference between Pozidriv and Phillips?

PZ and PH use different cross-recess geometries and require the correct matching driver. The wrong bit may reduce engagement and increase cam-out or recess damage.

What sizes can VALTOR supply?

Common diameters are approximately 3.0–6.0 mm, with selected 2.5 mm products. Commercial lengths are approximately 10–200 mm depending on diameter, thread, material and design.

Do Chipboard Screws require pilot holes?

Many applications can start directly, but pilot holes may be advisable near edges, in MDF or dense timber, with larger screws, or where splitting and alignment are concerns.
