Product Overview

300mm Hex Head Timber Screws for oversized timber beams and heavy landscaping structures. Each screw is made from heat-treated carbon steel for maximum torsional strength and long-term performance. 

A Ruspert-coated surface provides advanced corrosion resistance through a three-layer metallic system comprising a zinc base coat, chemical conversion film, and ceramic top layer.


The hexagonal drive head with integral washer face ensures high clamping pressure, preventing timber movement and pull-through under load. The coarse thread delivers fast cutting and high pull-out resistance in softwood, treated wood, and heavy sections.


A gimlet point - a self-tapping, tapered tip - allows for fast starting and penetration without the need for full pre-drilling, saving installation time while reducing timber splitting.

Features & Benefits

  • Material strength: Heat-treated carbon steel provides superior torsional and shear strength.
  • Ruspert coating: Three-layer corrosion protection (zinc, film, ceramic) ensures extended outdoor durability.
  • Hex washer head: Provides maximum grip for high-torque driving and broad surface contact for secure clamping.
  • Coarse thread: Rapid drive and strong hold in softwood, green oak, and pressure-treated timber.
  • Gimlet point: Self-starting tapered tip enables direct penetration and reduces splitting.
  • Nominal size: 300mm length.
  • Application range: Oversized timber beams and heavy landscaping structures.


Applications

  • Structural timber frames: Fixing deep beams and heavy assemblies.
  • Bridge decks and large sleepers: Long-reach structural joints.
  • Landscaping and civil timberworks: Suitable for large-section outdoor projects.


Installation Guidance

  • Pilot drilling: Recommended in dense or dry hardwoods for best accuracy.
  • Driving method: Use a power driver with compatible hex socket for consistent torque.
  • Head seating: Drive until the washer face seats firmly; avoid over-tightening.
  • Best practice: Maintain spacing between fixings to prevent end-grain splitting.


Compliance & Performance

  • Manufacturing reference: Produced in accordance with EN 14592 for timber fasteners.
  • Coating performance: Ruspert finish provides tested corrosion resistance suitable for standard exterior exposure.
  • Safety: Use eye protection and stable work support when fixing.
  • Important note: For coastal or permanently damp installations, stainless steel fixings are recommended.

How delivery works

We work with a nationwide network of trusted suppliers. Items in your basket may be supplied by different suppliers and delivered separately. Where this applies, you will see delivery charges shown at checkout for each part of your order. We always aim to group products from the same supplier to keep delivery costs as low as possible.

Delivery areas

Delivery charges apply to mainland UK, excluding: AB, CA, CF, DD, DG, EH, EX, FK, KA, KW, KY, IV, LA, LD, LL, ML, NP, PA, PH, PL, SA, SY, TR, TQ and TD.

If your address is in one of these areas, we will contact you before processing your order to confirm any additional costs. We do not currently offer delivery outside the UK mainland.

What to expect on delivery day

  • Deliveries are typically kerbside.
  • Please ensure someone is on-site to accept delivery. For heavier items, help with offloading may be required.
  • Many building materials arrive on large vehicles. If access is restricted, a specialist vehicle such as a HIAB may be required and could incur an additional charge.

Why delivery can cost more than typical parcel delivery

Building materials often travel on larger vehicles and usually carry fewer drops per run than parcel networks. That is why delivery charges can be higher than standard e-commerce shipping.

Returns

Returns depend on what you have bought and whether there is anything wrong with it. For full details on eligibility, timeframes, and exclusions, please see our full policy.
