to have a pair of faces of the same type in each individ-
ual grip.
To install these faces in the Screw Grips, perform the fol-
lowing:
(a) Select a type of grip face compatible with the type of
specimen you will be testing.
(b) If other grip faces are already installed in the grips,
remove them by loosening the two socket head set
screws in the sides of each grip face (four screws, in
all), using the 1.5 mm hex wrench supplied with the
grips. See Figure 4-2.
(c) Slide the grip faces out of the grips.
(d) Position each of the new grip faces in the body of the
grip over the end of the screw shaft. Tighten the
socket head set screws while holding the face in
place, using the 1.5 mm hex wrench. There should be
a small amount of movement of the grip faces when
the set screws are tightened properly.
Loading Specimens
To load specimens into the grips, do the following:
(a) Open both upper and lower grips by unscrewing both
thumbscrews on each grip.
(b) While holding the specimen in place in the upper
grip, tighten both thumbscrews of the upper grip
enough to hold the specimen. Ensure the specimen is
centered forward-to-back in the grip. Do not fully
tighten the thumbscrews at this time.
