Why Choose Spax Fixings & Fasteners?

Spax fixings and fasteners stand apart through their commitment to solving practical problems with engineered solutions. The signature 4CUT point features four cutting edges that score timber fibres cleanly, virtually eliminating splitting even near board edges and allowing screws to bite immediately without wandering or pre-drilling in most applications. This translates directly into faster installation and reduced material waste on site.

The T-STAR plus drive recess is another Spax innovation that prevents cam-out and bit wobble, enabling single-handed driving and reducing user fatigue during extended use. Unlike Phillips or Pozidriv heads, the T-STAR plus design maintains positive engagement even at awkward angles, whilst the Spax bit magnetism ensures screws stay firmly attached during positioning. Tradespeople consistently report that Spax screws drive faster and more reliably than conventional alternatives, with significantly reduced risk of damaging the drive head – a crucial advantage when working with premium materials or in visible locations.

Corrosion protection is equally impressive across the Spax range. Their proprietary WIROX coating provides up to four times the rust resistance of standard zinc-plated screws, making Spax fixings suitable for external applications, treated timber, and moisture-prone environments. For the most demanding conditions, Spax offers A2 and A4 grade stainless steel options that deliver uncompromising performance in coastal, chemical or high-humidity environments where standard fasteners would fail prematurely.

Safety and Compliance

Spax fixings and fasteners comply fully with relevant British and European standards for mechanical fasteners, including BS EN 14592 for timber connections and BS EN 14566 for mechanical properties. All Spax products undergo rigorous testing to ensure consistent performance and reliability in accordance with Construction Products Regulation (CPR) requirements.

When using Spax fixings and fasteners, always follow manufacturer guidelines for appropriate screw length, diameter and fixing spacing based on material type and loading conditions. Whilst Spax screws significantly reduce splitting compared to conventional fasteners, edge and end distances specified in structural design codes should still be observed for load-bearing applications. Eye protection should always be worn when driving screws with power tools, and appropriate drill bits should be used when pre-drilling is specified for hardwoods or pilot holes.

For structural timber connections, consult the relevant building regulations and structural engineering specifications to ensure correct fastener specification, particularly for critical applications such as joist hangers, truss connections and beam fixings. Spax provides comprehensive technical documentation and load data to support compliance with UK Building Regulations and Eurocode 5 timber engineering standards.

Frequently Asked Questions

Do Spax screws really not need pre-drilling?

In most softwood, chipboard and composite applications up to approximately 5mm diameter, Spax screws with 4CUT point technology can be driven directly without pre-drilling, even relatively close to board edges. This is due to the cutting action of the point which scores fibres cleanly rather than forcing them apart. However, in hardwoods, extremely dense materials, or when working very close to edges, pilot holes may still be beneficial to prevent splitting. For screws above 6mm diameter or in critical applications, pre-drilling is recommended regardless of material type.

What's the difference between yellow-zinc and WIROX coated Spax screws?

Yellow-zinc coating provides basic corrosion protection suitable for internal applications and dry environments. WIROX coating is Spax's proprietary finish that delivers approximately four times greater corrosion resistance – sufficient for external use, treated timber, and moisture-prone areas like bathrooms and kitchens. WIROX screws are ABC certified for outdoor performance. For the most demanding conditions including coastal locations or chemical environments, Spax offers A2 or A4 stainless steel options which provide uncompromising long-term durability.

Can I use standard Torx bits with Spax T-STAR plus screws?

Whilst standard Torx bits will fit Spax T-STAR plus screws, genuine Spax T-STAR plus bits are specifically designed to optimise performance with Spax drive recesses. The matched profile ensures maximum torque transmission, reduces bit wear, and provides superior cam-out resistance. Spax bits also feature enhanced magnetism for secure screw retention during single-handed driving. For professional results and extended bit life, Tooled-Up recommends using genuine Spax drive bits with Spax fasteners.

Are Spax fixings suitable for structural timber connections?

Yes, Spax construction screws are engineered specifically for structural applications and come with comprehensive technical data including withdrawal loads, lateral loads and characteristic values for use with Eurocode 5 calculations. They meet BS EN 14592 requirements for timber fasteners and can be specified for structural connections when used in accordance with manufacturer guidelines and relevant building regulations. However, structural applications should always be designed or verified by a qualified structural engineer who can specify appropriate fastener type, size, spacing and edge distances for the specific loading conditions.

How do I choose the correct Spax screw length for my application?

As a general rule, the screw should penetrate at least 2/3 of its length into the base material for secure fixing. For example, when fixing 12mm board to timber framework, a 40mm screw would provide approximately 28mm penetration into the base timber. For load-bearing applications, consult Spax technical documentation which provides specific penetration depth recommendations based on loading conditions. Partial thread screws are ideal for clamping applications where you want pull-down force, whilst full thread screws work better when fixing into thinner materials or when you need consistent holding along the entire shank length.
