HY 220277

Frequently Asked Questions

Q: What are the thread specifications for HY 220277?
A: The HY 220277 features metric M12 x 1.75 threads with a hexagonal head design. This is a metric coarse-pitch fastener suitable for Hyster equipment assemblies requiring ISO standard thread specifications.

Q: What material is HY 220277 made from?
A: HY 220277 is manufactured from alloy steel per ISO 898-1 Class 10.9 specification with Rockwell C32-39 hardness. This material grade is engineered for high-strength mechanical fastening applications on electric lift trucks where load-bearing capacity is critical.

Q: What equipment does HY 220277 fit?
A: HY 220277 is an OEM specification fastener for Hyster electric lift truck applications. The M12 x 1.75 metric thread and Class 10.9 strength make it suitable for high-strength mechanical fastening points. Verify compatibility with your specific Hyster model before ordering.

Q: Why is Class 10.9 hardness important for this fastener?
A: ISO 898-1 Class 10.9 fasteners have higher tensile strength and load-bearing capacity compared to lower grades. The Rockwell C32-39 hardness range indicates a fastener designed to resist fatigue and vibration in demanding applications like electric lift truck drive systems and structural assemblies.

Q: Are there substitutes for HY 220277?
A: Substituting fasteners without OEM validation risks equipment failure, warranty issues, and safety violations. HY 220277 is the OEM specification. If you need a replacement, use the exact Hyster part number. Contact us to verify if your equipment model is compatible with this fastener.
