Advanced Coach Screws – Hex Flange Head (Zinc & Yellow Passivated)

Advanced Coach Screws are engineered for tough jobs where strength and speed matter. Designed with a modern hex flange head and aggressive slash point tip, they’re the next-generation alternative to the traditional DIN 571 coach screw. Suitable for fixing into softwood, hardwood, man-made boards or even masonry (with nylon plugs), these screws deliver fast, reliable results.

✔ 3x faster to install than standard coach screws
✔ Single slash point cuts down splitting and makes driving easier
✔ Compatible with power tools for efficient fixing
✔ Zinc plated and yellow passivated for improved corrosion resistance

What are Coach Screws Used For?
Also known as lag screws, coach screws are designed for high-strength applications like securing timber to timber, or metal to timber. They’re ideal for structural work, landscaping, fencing, decking and more.

Understanding Sizes
Coach screws are measured by diameter and length. For example, an 8 x 100mm screw has an 8mm thread diameter and is 100mm long from tip to the base of the hex head (excluding the head itself, which sits above the surface when installed).

We supply Advanced Coach Screws in common diameters:
6, 8, 10, and 12

Lengths range from:
25mm up to 160mm
(Not all diameters are available in every length – check individual listings.)

Choosing the Right Finish
At Fast Fixings Online, our Advanced Coach Screws come zinc plated and passivated for moderate corrosion protection – great for interior and some exterior use.

Installation Tips
To get the best results:

• Drill a pilot hole: half the screw diameter for softwoods, three-quarters for hardwoods
• Use the correct socket or spanner to drive in the screw
• Consider using washers to avoid damaging the timber surface
• Take care not to overdrive or strip the head
