Frequently Asked Questions
Q: What size and thread pitch is hex head nut 3738415?
A: Hex head nut 3738415 is a 0.75 inch diameter with 10 threads per inch (coarse pitch). This size is standard for load wheel axle fastening on manual and electric pallet jacks from multiple OEM brands.
Q: What material grade and strength is nut 3738415?
A: Hex head nut 3738415 is Grade 8 zinc-plated steel. This grade provides high tensile strength and corrosion resistance suitable for warehouse and dock environments. Grade 8 fasteners are appropriate for bolted wheel assemblies that experience vibration and dynamic loads.
Q: Which pallet jack models use hex head nut 3738415?
A: Hex head nut 3738415 is used in axle assemblies on manual pallet jacks from Crown, Toyota, Raymond, and Yale. It is also found in some electric lift truck wheel hubs. Verify the bolt diameter on your equipment matches 0.75 inches before ordering.
Q: When should hex head nut 3738415 be replaced?
A: Replace hex head nut 3738415 if threads become stripped, the nut does not hold tightness after 24 hours, or visible corrosion extends deeper than surface rust. If a load wheel rotates freely on the axle, the nut is likely the cause and should be replaced immediately.
Q: Is hex head nut 3738415 available in stainless steel?
A: Nut 3738415 is zinc-plated Grade 8 steel. For cold storage or marine environments requiring stainless steel, contact our parts team for a stainless equivalent. Stainless fasteners may have different thread pitch or size availability.
Q: What torque specification should be used when installing hex head nut 3738415?
A: Refer to your equipment manual for exact torque specifications. For Grade 8 hex nuts on 0.75 inch bolts, typical torque ranges from 40 to 60 foot-pounds depending on the specific application. Do not over-tighten, as this can strip threads or distort the bearing.
