Comparing prices will also ensure companies can’t take advantage of you and give you a fair price. 4. Word of Mouth Passivated (or zinc plated) coach screws are electroplated using a zinc coating. Many of our passivated products are then finished in yellow chromate. Passivation offers increased corrosion resistance, although for maximum corrosion resistance use a galvanised screw. Unlike the galvanised option, however, passivated screws typically have a high-shine finish. These are ideal for applications where aesthetics are important. Browse our range and you’ll typically see three types available: passivated, galvanised and stainless steel.

How do you choose the right coach screws for your application? And how do you select the right coach screw sizes? Also known as lag screws or lag bolts, they are heavy-duty screws that are designed for metal to timber connections, or to join heavy timbers. The best way to find a great insulation installer is through recommendations. Make sure you ask friends and family. They will most likely give you their honest opinion and can tell you from first hand experience.

So, if you’re working with pine and you’re using a 12mm (M12) screw, drill a 6mm pilot hole. For the same screw in mahogany, make the pilot hole 8mm. To avoid overdriving the screw when working with timber, use a washer.

No matter whether you choose a local installer or a national company, there’s a few tips to help you find the right installer for your home insulation improvements, such as asking for recommendations and making sure that they’re part of a certification scheme. This makes sure that they have the right skills and standards of workmanship to carry out the installation, and you can be sure that they know exactly what they are doing. 4 TIPS FOR CHOOSING THE BEST INSULATION INSTALLER 1. T hermal inspection picture in portfolio Coarse Thread Design: The coarse thread of chipboard screws allows for a stronger hold and increased resistance to pull-out forces. This design ensures that your fastened materials remain securely in place, providing long-lasting durability. Reliable Fastening: With their specially designed threads, chipboard screws offer reliable and long-lasting fastening for soft timbers, MDF, and chipboard. The screws bite into the material, creating a tight and secure grip that minimises the risk of loosening over time. So, for example, a screw with the dimensions M8 x 100mm is 8mm in diameter at the thread’s maximum width and 100mm in length from the screw tip to the base of the screw head. The screw head itself remains proud of the drill hole.After fiddling with spares and bodges on ancient and worn out door handle I finally found one in similar dimensions at Handles and Hinges. Fitted in 5 mins and works a treat

Versatile Applications: Chipboard screws are ideal for a wide range of woodworking projects.

Lag screws have two measurements. The M rating is the diameter of the screw thread; the measure in mm is the length of the screw from screw tip to the underside of the hexagonal head. Galvanised coach screws are zinc-coated, low-cost steel screws. Typically a matt finish, these screws are often used in automotive parts, sheet metals, industrial applications and construction. The zinc coating offers corrosion resistance. This makes galvanised coach screws suitable for outdoor, hot, wet and humid environments. To avoid splitting timbers, drill a pilot hole before inserting any screw. Pilot holes should be half the diameter of the screw when using softwoods, and three-quarters its diameter when working with hardwoods. Chipboard screws are engineered with precision to provide exceptional fastening capabilities for soft timbers, MDF, and chipboard. These screws feature a single thread that extends from the base of the head to the tip on smaller sizes. The coarse thread design creates a larger distance between each peak, ensuring enhanced grip and stability. Stainless steel coach screw types are great for outdoor use. Because there’s no coating, the corrosion resistance comes from the screw’s composition. Stainless steel coach screws are our most durable type and are also resistant to the oils and acids in many timbers.
