2207 Power Twist Universal V Nails 7mm Hardwood 4000

Engineered to give the tightest corner join

For most brands of underpinners including Cassese Uni, Inmes, Pistorious, Unimatic, Gielle, Morso, Brevetti Delta, Taurus, Framers Corner and others.

Power Twist V Nails have been engineered by Alfamacchine to achieve the tightest corner join. The tapered shape and elasticity of the steel makes the V Nail twist outwards as it enters the moulding, once inserted the V Nail pulls the mitred edges together as it contracts to return to its original shape, resulting in a tightly closed corner join.

Power Twist Universal V-Nails are 10.3mm wide and fit most brands of Underpinners including Inmes and Cassese. They are sometimes referred to as UNI Wedges by other manufacturers. 

We recommend Power Twist V Nails for framers of any level because they consistently help achieve a tighter corner join, stay perfectly straight and reduce jamming. V Nails are a relatively low cost element of making a frame, so we suggest using the best.  

+ Power Twist Design Technology
The patented taper shape of Power Twist V Nails, twists outwards as the V Nail is inserted into the moulding, which then pulls the join tightly together once inserted as it contracts to return to its original shape.  

+ Consistent High Quality Steel Construction
The same exceptional quality control and detailed design that Alfamacchine Underpinners are renowned for, goes into their V Nails. Power Twist V Nails are made from only the best carbon steel and as a result they stay consistently straight when inserted. This is particularly useful in timber with variable grain such as Finger Jointed Pine.

+ Silicone Coating Formula
A silicone formula is used to stack the wedges rather than adhesive, as the residue from adhesives is a common cause of jamming in the firing mechanism of Underpinners. The silicone also acts as a lubricant, ensuring V Nails slide smoothly into the moulding. 

+ Available for Normal or Hardwood
Power Twist Universal V Nails are available for both Normal and Hardwood. The silicone on the V Nail strips is colour coded for easy identification. Clear for Normal, Brown for Hardwood.

+ Available in Five Different Sizes
Available in 5, 7, 10, 12 & 15mm.
