Answer 6

4.83 mm or less is light-duty. 4.83 and over is heavy duty

Question 7

What is a tension load

Answer 7

A tension load applies force to the fastener perpendicular to the base material surface. Or away from the base

Question 8

What is a shear load

Answer 8

A shear load applies force to the fastener perpendicular to the pin.

Question 9

What is a bending load

Answer 9

I shear load force is applied at a distance from the surface of the base material creating a lever type action on the Fastner

Question 10

What are some unsuitable base materials

Answer 10

Brick slate and rock

Question 11

How was your test material before shooting into it ?

Answer 11

The center punch test. Use a Fastner as a punch hit the faster with a single hammer blow and see if the tip was blunted or if it made an imprint on the material

Answer 14

7 days it is at 65%_75% of it’s max strength

Question 15

Never attempt to fasten into a….

Answer 15

Spalled or cracked area or where previous Fastner has failed

Question 16

How could you eliminate minimize fish hooking

Answer 16

Reduce shank penetration, increase Shank diameter, ensure that the Fastner is not being overdriven
