Frequently Asked Questions
Q: What is the HJ 151 washer used for in pallet jacks?
A: The HJ 151 is a washer used under fastener heads or nuts to distribute load and prevent fasteners from digging into softer materials such as nylon hub or plastic components. It is commonly found in wheel assembly attachment points.
Q: What material is the HJ 151 washer made from?
A: Standard replacement washers for pallet jack assemblies are typically steel or stainless steel. For applications in corrosive or wet environments, stainless steel is preferred. Verify material and finish specifications with your equipment manual.
Q: What fastener sizes does the HJ 151 washer work with?
A: Washer compatibility depends on the inner diameter (bore size) and outer diameter. Provide your fastener size (bolt diameter) or equipment model number to our parts team to confirm the correct washer specification.
Q: Is the HJ 151 washer reusable?
A: Steel washers can be reused if they show no permanent deformation, corrosion, or surface damage. If the washer has bent edges, rust, or is significantly flattened, replace it with a new HJ 151 washer to maintain proper fastener grip.
Q: Can the HJ 151 washer prevent loose fasteners?
A: The HJ 151 washer distributes clamping force and prevents fasteners from loosening due to compression of soft materials. However, a washer alone does not prevent loosening from vibration. Use a nylon-insert locknut or locking screw such as HJ 146 for vibration resistance.
