Dual Thread Wood Screw with Left hand thread for 4mm Cable

This Dual Thread Wood Screw with Left Hand thread is our most suitable wood screw fitting to be used into wood. It goes with the Left Hand Swage socket. The wood screw system is the perfect system (Option 3: Wood screw to Wood screw) to tension your balustrade cables where you want to go into your wooden end posts but not go all the way through the wooden end post. It is also suitable where you want to terminate into a corner post and not go all the way through the post. 

The total length of the screw is 80 mm long from end to end and it is 6 mm thick with a left hand thread for the left hand nut. The thread that disappears into the wood is 40 mm long and the thread that remains exposed is suitable for Left hand threaded swage sockets and nuts to screw onto. When you purchase this system please remember that one cable will consist of four separate fittings: 2 with left hand thread and 2 with right hand thread.

Fittings required for this system:

1. Dual Thread Wood screw with Right hand thread 
2. Swage socket with right hand thread for 4 mm cable
3. Dual Thread Wood screw with Left hand thread 
4. Swage socket with left hand thread for 4 mm cable

Installation:

This Dual Thread Wood Screw will require you to drill a small pilot hole into your wooden posts. Rule of thumb: A smaller pilot hole for soft wood and a bigger pilot hole for very hard wood.

This Dual Thread Screw is only suitable to use with Left hand threaded Swage sockets that can take a 4 mm cable. The Dual Thread Screw will go into you post to a depth of 40 mm deep and the steel thread remains exposed for the female swage socket to be turned onto the thread of the screw.

We are a Proudly South African company and therefore most of our balustrade fittings are locally manufactured by us here in Cape Town out of the highest Grade of 316 Stainless Steel available.

Our Balustrade cables are suitable to be used on interior staircases, balustrades and lofts. Cables are also extremely popular outside on balustrade decks, balconies, walkways, staircases, Pergolas & Juliet balconies.

The steel fittings are suitable to be used in conjunction with a range of natural woods like, Balau, Garapa, Rhodesian Teak, Saligna and Pine wooden decking.

Synthetic decking and composite wood decking products are also very popular and are sometimes preferred over natural wood. This is due to requiring less maintenance and due to engineered wood products are resistant to rotting, splintering and warping.
