Screw Tip Assemblies of GX
We have an extensive CAD library consisting of thousands of prints
for screw tips, barrels, screw, nozzles, end caps, etc. If you need
a quote and there isn't a print available, simply send us a used
sample part and specify what material you want the new one made
from. (Hint: Always save your original screw tip assemblies. They
are valuable for verification of dimensions when ordering new
assemblies.)
No one check valve design is perfect for every application;
therefore, we offer three distinct designs to ensure the proper
component for your application.

Material Options:
H-13 Tool Steel
A good high strength pre-hardened tool steel which is machined,
thru-hardened, and ground dimensionally, then nitride hardened for
72 hours for better wear resistance. H-13 is tough and can handle
pressure and torque.
D-2 Tool Steel
A high carbon/high chrome tool steel with good wear resistance, but
low on torque strength. D-2 should only be used with 4-piece
designs where the stud is manufactured from 4140, H-13 or another
high torque steel.
CPM-9V Tool Steel
A new generation tool steel with a high percentage of Vanadium
Carbide developed for high wear (abrasive) applications. It resists
wear from abrasive fillers in resin. (Construction: Carbon 1.8%,
Manganese 0.50%, Silicon 0.9%, Chromium 5.25%, Molybdenum 1.3%,
Vanadium 9.0%.)
CPM®-420V Tool Steel
Crucible's CPM-420V is a new stainless tool steel best suited for corrosion
resistant applications. CPM®-420V is a higher performance upgrade from CPM®-440V. Corrosion resistance is significantly better than CPM®-440V. Wear resistance is about 25-50% better than CPM®-440V, due to the higher Vanadium Carbide content of CPM®-420V (9% Vanadium vs. 5.5-6% in CPM®-440V).
CPM®-M4 Tool Steel
Crucible's CPM-M4 is a high Vanadium, special purpose, high speed steel
exhibiting better wear resistance and toughness than D2 or CPM®-9V. CPM®-M4 has a hardness rating of 64.0. (Construction: Carbon 1.42%,
Chromium 4.0%, Vanadium 4.0%, Tungsten 5.5%, Molybdenum 5.25%.)
