Product Overview

Traditional Wood Screws are designed for fastening solid wood, timber, furniture components and compatible wood products. Their sharp point and wood-thread geometry support starting and engagement, while many traditional designs use a partially threaded body with a smooth upper shank. Different softwoods, hardwoods and panels require suitable screw diameter, pilot-hole preparation and edge distance.

The smooth shank can pass through an upper component while the threaded section engages the base wood, helping draw the joint together when the geometry is suitable. Full or extended thread versions may also be supplied where required, but neither thread form guarantees performance without considering wood density, component thickness and installation.

Buyers should specify head, drive, diameter, length, thread length, material, finish, wood species, component thickness, application, quantity and any DIN or drawing requirement. DIN geometry should only be claimed where the actual head, drive and dimensions comply.

Technical Specifications

Structural Limitation
DIN 95 / 96 / 97 / 7995 / 7996 / 7997 products are not automatically approved structural timber screws; approved products and verified documentation are required for load-bearing design.

Wood Thread, Pilot Hole & Joint Selection

Wood Thread & Point
Thread form and sharp point support wood engagement, but performance depends on material density, diameter, engagement and installation.
Smooth Shank Function
The upper member can move along the smooth shank while the threaded section engages the base, helping draw a suitable joint together.
Pilot Holes
Recommended evaluation is especially important in hardwood, dense timber, larger diameters, stainless-steel installation and locations near edges.
Softwood / Hardwood
Softwood generally offers lower driving resistance; hardwood commonly requires careful pilot-hole and diameter selection to reduce splitting and fastener damage.
Head & Drive
Countersunk seats flush; raised countersunk leaves a modest decorative dome; round head remains proud. PH, PZ and slots require matching tools; Torx is a selected modern/custom option.
Wood vs Chipboard Screws
Traditional Wood Screws are a broad solid-wood family often using a smooth shank. Chipboard Screws typically use a slimmer core and deep coarse thread optimized for particleboard and MDF. Selection depends on material and joint design.

Technical note: These traditional DIN Wood Screw families are intended outside applications requiring structural construction approval. Use an appropriately approved Structural Wood or Timber Screw with verified documentation for load-bearing design.

Material, Head & Size Options

304 Stainless Steel — For furniture, equipment wood components, general corrosion-resistant assemblies and suitable exterior applications.
316 Stainless Steel — For improved resistance in outdoor, humid, coastal and more corrosive wood assemblies.
Carbon Steel — For general joinery, furniture and cost-sensitive interior production with suitable finishes.
Head Options — Countersunk, raised countersunk and round head according to DIN family or customer drawing.
Size Range — Main diameter 3–8 mm and length 10–150 mm; not every diameter is available in every length or head configuration.

Drive, Thread Length & OEM Manufacturing

Drive — PH, PZ, slotted and selected 6-lobe supply. PH and PZ are different; Torx options are not automatically traditional DIN products.
Thread & Shank — Traditional partial thread, full/extended thread or customer-specified thread and smooth-shank length.
Custom Geometry — Head diameter, height, countersunk profile, shank and thread start may follow a drawing; non-DIN dimensions are described as custom Wood Screws.
OEM Input — Provide head, drive, diameter, length, thread length, material, finish, wood, thickness, application, quantity and drawing/sample.
Packaging — Inner bags, small boxes, export cartons, bulk packs, customer labels, part numbers and authorized private labels.

Wood Fit, Installation & Quality Control

Dimensional Inspection — Check diameter, length, thread length, shank, head diameter and head height.
Thread, Point & Drive — Verify profile, continuity, thread start, point concentricity, burrs, PH/PZ geometry, slot dimensions or 6-lobe engagement.
Head Inspection — Confirm countersunk, raised-countersunk or round-head profile and correct seating geometry.
Installation Samples — Softwood, hardwood, plywood or customer components may be evaluated for starting, seating, splitting, engagement and closure.
Documentation — MTC, raw-material, dimensional and inspection reports, sample installation records and third-party support where ordered.

Frequently Asked Questions

What is the difference between Wood Screws and Chipboard Screws?

Traditional Wood Screws are a broad family for solid wood and often use a partial thread with smooth shank. Chipboard Screws typically use a slim core and deep coarse thread optimized for particleboard and MDF.

Do Wood Screws need pilot holes?

Pilot holes are especially useful in hardwood, dense timber, larger diameters, stainless-steel installations and locations close to edges.

What sizes can VALTOR supply?

Common Wood Screws are approximately 3–8 mm in diameter and 10–150 mm long, with broader 2–10 mm coverage depending on standard and head.

What is the difference between DIN 7997 and DIN 97?

DIN 7997 specifies cross-recessed countersunk Wood Screws in 2–8 mm, while DIN 97 covers slotted countersunk flat-head Wood Screws in 1.6–10 mm.

Should I choose 304 or 316 stainless steel?

304 suits many general corrosion-resistant assemblies, while 316 is commonly selected for more demanding outdoor, humid or coastal conditions.
