Frequently Asked Questions
Q: Which Hyster models are compatible with the HY 16820 lug bolt?
A: The HY 16820 lug bolt is designed for Hyster W 40 XL and Hyster W 40 XT electric lift trucks. It fastens wheel assemblies with hex head fastening. Verify your exact model designation before ordering to confirm fitment.
Q: What are the exact specifications of the HY 16820 lug bolt?
A: The HY 16820 is a Grade 8 hex head lug bolt with 1/2 inch diameter, 1/2-20 UNF thread pitch, and 1 inch length. These specifications meet OEM standards for Hyster electric lift truck wheel assembly fastening. Cross-reference part numbers: 16820, Hyster 16820, HY16820.
Q: Why is Grade 8 material important for the HY 16820?
A: Grade 8 fasteners provide high tensile strength and load-bearing capacity required for wheel hub fastening on lift trucks. This material grade ensures fastener reliability under the repetitive stresses and lateral forces generated during loading, turning, and braking operations.
Q: How many HY 16820 bolts are needed per wheel assembly?
A: Wheel hub configuration varies by model. Hyster W 40 XL and W 40 XT trucks typically use multiple lug bolts per wheel. Consult your equipment manual or technical schematic to determine the exact quantity required for your assembly.
Q: Are there equivalent lug bolts that work as substitutes for the HY 16820?
A: Standard Grade 8 fasteners with 1/2 inch diameter, 1/2-20 UNF thread, and 1 inch length meet specification. However, we recommend using OEM Hyster HY 16820 or verified cross-reference part numbers to ensure exact fit and load rating compliance.
Q: What fastener torque specification should I use with the HY 16820?
A: Consult your Hyster W 40 XL or W 40 XT technical manual for the exact torque specification. Do not rely on general Grade 8 fastener recommendations—OEM specifications account for hub material, design, and safety requirements specific to your lift truck model.
