Screw Tip Assemblies
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%.)
