Non Prismatic Grooved Shank Fastener for WOOD

  Non Prismatic Grooved Shank nails provide improved holding power in lateral and withdrawal loads.

NPGS-1

USE in
SIMPLEX JOINTS
with two
elements.

 

 

 


Protected under one or more patents pending.

NPGS -2

USE in
COMPOUND JOINTS
with two or more
elements

 

 

 

NPGS NAILS
  • Minimize wood distortion and splitting.
  • Increase the area of shank contact in the wood.
  • Increase joint holding power.
  • Decrease number of nails required.
  • Offer longer joint life, more

Compare NPGS load capacities with Standard Wire Nail sizes
Safe Working Loads for NPGS nails are conservatively assigned based upon the joint deflection of the same weight wire nail.

GREATER HOLDING POWER
BETTER JOINT EFFICIENCY
SAME COUNT PER POUND



The NPGS is configured to optimize the contact area of the nail which opposes the joint movement. Although the shank is grooved, nail efficiency is unaffected by alignment of the grooves to the direction of load.

NON PRISMATIC GROOVED SHANK FASTENER




NPGS-1 nails are designed for use in simplex joint arrangements where two elements are connected.

NPGS nails are sorted according to nail count per weight and length, compared to standard wire nails.

Nominal diameter of NPGS is measured at the widest portion of the shank.

Joint efficiency is indicated in how quickly the joint distortion returns to zero as the load is removed

NPGS-2 nails are designed for use in COMPOUND joint arrangements where two or MORE elements are connected.

The NPGS is configured to optimize the contact area of the nail which opposes the joint movement. Although the shank is grooved, nail efficiency is unaffected by alignment of the grooves to the direction of load.

Both types 1 and 2 of the NPGS shank can be mechanically deformed at the lower point of the shank taper. This creates shoulders in the ridges which offer a resistance when the shank is subjected to a withdrawal tension.
