Bolt Fixtures (4)


H900 condition. It is now nice and toasty.
~50% higher yield strength than
the as-received material

Slowly air cooled on a broken piece of
ceramic cruicible

Now I have fixture for breaking bolts
busting stuff is always edumakational

The bolt fixture fits well in
the MTS 810 (55 kip) frame

The side slots are for quick and
easy loading of bolt specimens

1/4"-20 nut and bolt set (SAE grade 5)
is placed in the holder

Actuator pulling the bolt apart
