About Carpenters Mate

We manufacture and supply fasteners and wood connectors that outperform conventional screws, bolts, ties and nails.

We’re a British company, established in 1998 to distribute FastenMaster self-drilling fasteners, manufactured in the USA. We’re still the exclusive importer and distributor for the entire product range.

We’re proud to say that our Carpenters Mate self-drilling screws and fasteners have taken the UK trades market by storm.

We’re always working on new products, talking to carpenters, builders and other tradesmen to find out what they really need to make their work faster, easier, safer and stronger.

We take a huge amount of pride in the quality of our workmanship, and every single Carpenters Mate product is designed and manufactured not only in accordance with the strictest guidelines and regulations, but in accordance with market need. Our customers know they get a product they can stake their reputation on – and we provide full technical specifications and technical product support for total reassurance.

Product FAQs

Our products are custom designed by people who truly know what carpenters need – carpenters themselves. So, if you’ve got questions, we’ve got the answers. Check out our FAQs below or call 0845 241 9862.

Carpenters Mate wood screws help make laying flooring and decking, completing loft conversions, constructing roofs and erecting fences quicker, cleaner and easier than ever before. They’re ideal for any project that requires a strong timber-to-timber connection.

Yes – Carpenters Mate screws are just as strong, if not stronger than coach bolts timber connections. Our screws are all EN 14592 Compliant so you can be sure that your timber structure is extremely secure. You can use the CalcuMate App to see how many screws are needed for each joint to meet the industry standard.

If you’re not sure how many Carpenters Mate Pro Hex screws you need for your loft conversion, CalcuMate can help! CalcuMate is our easy-to-use online loft conversion and multiple member spacing calculator that makes it super easy to calculate how many screws you need to get the job done. And best of all, it’s completely free!

Simply enter the requested information about your conversion, such as the roof pitch and number of bolts to replace, select the type of join and CalcuMate will work out how many screws you need to complete the project. You can also save your calculations and view them at any time – making it the ideal loft conversion calculator for carpenters and tradesmen. Visit http://www.mycalcumate.co.uk and make planning your loft conversion a piece of cake.

Carpenters Mate screws are engineered to ensure they work, every time. Our Pro Hex Head screws and HD Hex Head Screws are made from C1022 steel, which has a higher carbon and manganese content than C1020 providing greater strength and ductility. We also offer a grade 316 stainless steel hex head screw that has a higher % of titanium for increased anti-corrosion properties. The screws are also case hardened which, as the name suggests, provides a hardened case for ease of drilling whilst still retaining ductility to move without snapping.

Fixing timbers together using the more traditional coach bolt method is a tried and tested approach that works, but you’ll need a drill, a hammer, washers, nut and bolt and a spanner for the job. On top of this, you’ll need to drill a hole into your timber, line up the intermediate washer, hammer the bolt through the hole, place the square washer on the back and finally tighten the nut, and repeat. This is a lengthy and tedious process – and that’s if you can access the back of the timbers! With a Carpenters Mate screw, simply zip the screw into the two adjacent timbers and that’s it! No washers, no predrilling, no hassle.

It’s a very good product, super easy, super efficient to use. We use them on every single one of our projects and love them!

Having a Sales Manager who is passionate and cares about the product and company they work for makes the difference. Our account manager is enthusiastic and wants us to sell their products and maximise growth. They put the time and effort in to help us achieve sales and nothing is to much trouble, the product sells itself but it needs people to do the rest.

The product sells its self, it saves time if customers are using Coach Bolts as its BBA Approved and stamped. Once customers try the product they don’t normally want to use anything else.

As a retailer all the products I purchase through OSC are of outstanding quality with an order service second to none on deliveries which is a huge benefit to our company which I pass on to my customers

The spider drive bits arrived this morning in the post. I cannot thank OSC enough, I wish all companies had your sort of attitude to customer care. I will be sure to use you and recommend you in the future.

Carpenters Mate and particularly Clinton Butcher our local representative have been so helpful not only in merchandising but also identifying products missing from our ranges which have increased our sales and profitability

Always great quality and I have never had a snapped screw, the best!
