How to Fit Speaker Spikes

Introduction.

         There are a number of LOUDSPEAKER SPIKES of various lengths and thread sizes to suit most Loudspeaker Cabinet weights. Spikes are usually fitted in sets of four per cabinet, to maintain stability. A Wood Insert and Locknut are also required to complete the fitting.

Spike Materials.

        Different materials can be used to manufacture spikes. The most common being Steel, Stainless Steel and Brass. Common thread diameters are in metric sizes, and this determines the overall size and to a lesser extent the weight loading that each type can support. Spikes are available in M6, M8 and M10 thread pitch and generally range from around 32mm to 55mm in overall length.

Spike Surface Finishes

         Untreated Steel spikes tend to rust and so are usually processed with a chemical finish known as chemi-black. This finish is known as a cosmetic finish and is not suitable for exterior / outdoor use or in very damp conditions.
         Alternatively, a Chemical process known as BZP, (Bright Zinc Plate), can be applied which gives a shinny silver finish and is far more robust in adverse conditions. It is not, however, widely used.
        Gold plated finishes and nickel plate are other options but these types of plating make the items more expensive than simple CB (chemi-black) finish.
        Stainless steel Spikes are by nature more resistant to degradation and discolouration. They retain their machined finish well and being of a harder material and more awkward to machine and more expensive. Lastly, brass finished spikes take on their natural material colour but over time they tarnish and are usually coated with a transparent varnish coating. Even so this eventually fades so....

Wood Inserts for Spikes.

        WOOD INSERTS are available in two styles for fixing the speaker spikes to wood or composite materials. One style is based upon a press or push fit,  known as Knock-in wood inserts. They have good twist / rotational resistance. The head of the Knock-in has a robust flange or shoulder.
Whilst known as Knock-ins it's not a great idea to hammer them into MDF based wood materials as these are generally weak and may shatter.        The alternative, known as Screw-in wood inserts, have a sharp cutting thread and a small lipped flange to aid in depth setting.
       Tee Nuts are another type of self clinching fitting with three or four prongs. These close within the wood when hammered in and are resistant to twist. These items are all sold in packs of 8 pieces.

Spike Locknuts

        BLACKED Spike Locknuts are available to suit either M6 or M8 threads. Locknuts can be supplied as either Full Nuts or Half Nuts where Half Nuts are thinner and are best suited for use with short spikes. Locknuts can also be supplied in Stainless Steel, usually the Half Nut variety. Tee Nuts are another type of self clinching fitting with three or four prongs. These prongs are profiled to close within the wood when hammered in and are resistant to twist. These items are all sold in packs of 8 pieces.

Spike Kit

       Complete kits of Spike parts are available in M6, M8 or M10 thread, consisting of a loudspeaker spike, wood insert and locknut. These are also sold in packs of 8.

Spike Shoes

       The pressure generated at the tip of a loaded loudspeaker spike is considerable and can easily damage some surfaces like wooden floors. To protect wooden floors and shelves, blacked steel spike shoes 13mm diameter can be placed underneath the spike tip. larger Acetal spike shoes 24mm diameter and in three colours are available to enhance the visual appeal.
