Frequently Asked Questions
Q: What is the BI 12003923 and which pallet jacks does it fit?
A: The BI 12003923 is an OEM handle bolt with left-hand thread manufactured by Bishamon. It is designed for BS-55 manual pallet jacks to secure the handle pivot assembly. This is a factory fastener component, not a cross-brand equivalent.
Q: What material and strength grade is this handle bolt?
A: The BI 12003923 is constructed from high-strength steel meeting ISO Grade 8.8 or equivalent industrial fastener standards. This grade provides the tensile strength required for cyclic loading and manual material handling duty in hydraulic pallet jack applications.
Q: Why does this bolt use a left-hand thread?
A: The left-hand thread is a design feature that resists loosening under the operational torque generated by manual handle actuation. This anti-loosening characteristic maintains bolt tension during repeated lift, lower, and steer cycles, reducing the risk of assembly separation.
Q: What are the cross-reference part numbers for the BI 12003923?
A: Known cross-references include BI12003923 (no space format) and 12003923 (short number format). Bishamon documentation may reference this as BS-55 handle bolt assembly component. Verify part fit before ordering, as alternate Bishamon models may use different fastener specifications.
Q: How long does the BI 12003923 typically last in service?
A: As a hardened steel fastener, the BI 12003923 is designed for the life of the pallet jack under normal operating conditions. Service life depends on load frequency, environmental exposure, and maintenance practices. Replace if bolt shows corrosion, stripped threads, or visible deformation.
