Frequently Asked Questions

What fasteners does Macsim make?

Macsim produces a comprehensive range of fasteners and fixings including timber screws, self-tapping screws, treated pine screws, Type 17 screws, batten screws, hex head bolts and nuts, coach screws, dynabolts, masonry anchors, wall plugs, rivets, washers, window packers, roll wall plugs, and screwdriver bits. Products are available in zinc, galvanised, stainless steel (304 and 316), and brass finishes.

What is the difference between Macsim zinc, galvanised, and stainless steel screws?

Macsim zinc plated screws are suitable for interior applications where corrosion resistance is not critical. Galvanised screws offer improved corrosion resistance and are suitable for treated pine and exterior applications. Stainless steel screws (304 and 316 grade) provide the highest level of corrosion resistance and are recommended for coastal environments, marine applications, and any situation where long-term corrosion resistance is required.

Are Macsim treated pine screws suitable for decking and outdoor use?

Yes. Macsim produces a range of treated pine screws in galvanised finish specifically designed for use with treated pine timber in outdoor applications such as decking, fencing, and landscaping. Galvanised fasteners are recommended for use with treated pine as they resist the corrosive effects of the preservative chemicals used in treated timber.

Does Macsim make masonry anchors and wall plugs?

Yes. Macsim produces a range of masonry anchors and wall plugs including dynabolts (masonry expansion anchors), masonbolts, Macdrive metal anchors, masonry screws, and roll wall plugs in red and blue. These products are designed for anchoring into concrete, brick, and masonry substrates in a variety of load and application requirements.

Does Macsim make Type 17 screws for structural timber applications?

Yes. Macsim produces a range of Type 17 screws in galvanised finish, available in multiple sizes. Type 17 screws feature a special point design that drills its own hole in timber, reducing the risk of splitting and eliminating the need for pre-drilling in many structural timber applications. They are commonly used in roof and wall framing, purlins, and structural timber connections.

Packaged correctly

OK, its a globe. Switch it on, it lights up. Switch it off it goes dark.
The difference purchasing it from Double Bay Hardware makes is that the 2 I ordered were packaged as filament globes should be, lots of shock absorbing bubble wrap and clear labeling that the are fragile!

I couldn’t find a washing -up mop anywhere in my local town so I went online and Double Bay Hardware supplied three for me and had them packed and on the way the same day. I was most impressed. Many thanks.

Goldair 1200W radiant heater

This is an excellent heater. It’s practical, lightweight, easy to use and gives instant warmth as well as being affordable. The level of heat can be adjusted to one, two or all three bars. I highly recommended it. Fan from Double Bay Hardware was incredibly helpful and accomodating. Wonderful customer service. Cheers, Evelin.

Have only used 1, the other is spare as it is difficult to find these globes & the other one will probably blow any day now as they are connected to the same switch. Works as expected.
