Frequently Asked Questions
Q: What is the BT 111256 shoulder bolt and what does it do?
A: The BT 111256 is a shoulder bolt, also called an arm bolt, designed to serve as an arm pivot fastener in manual pallet jack linkage assemblies. It provides the rotational pivot point that allows the lift arms to move during raising and lowering operations.
Q: Which BT pallet jack models use the BT 111256 shoulder bolt?
A: The BT 111256 is engineered for BT Prime Mover manual pallet jack models. Verify your pallet jack model number and assembly location to confirm this part is the correct fit for your equipment.
Q: What material and hardness specifications define the BT 111256?
A: The BT 111256 is precision machined from alloy steel with a minimum SAE 1045 grade, case hardened to a minimum Rockwell C45. Metric thread design follows OEM specification ISO 2768-m tolerances. This hardness and material combination provides wear resistance and strength for thousands of pivot cycles.
Q: What specifications should I verify when ordering the BT 111256?
A: Verify that your pallet jack requires a shoulder bolt at the arm pivot location, confirm the metric thread size matches your equipment, and check that the bolt length accommodates both lift arms. OEM part number BT 111256 is machined to precise BT tolerances.
Q: When should the BT 111256 shoulder bolt be replaced?
A: Replace the BT 111256 if you notice excessive play at the arm pivot, difficulty moving the lift arms, visible wear, or if threads are stripped or damaged. Case hardening protects against wear, but mechanical damage or deformation requires immediate replacement to maintain safe lift arm operation.
