🪛 Product Description
M6 nylon shoulder washers are designed for insulating and spacing M6 bolts and screws in mechanical, structural, and electrical installations. Manufactured from high performance PA66 nylon, they provide dependable electrical isolation while preventing direct contact between fasteners and surrounding materials.
Often referred to as insulation bushes or top hat washers, the integrated shoulder section locates inside the mounting hole and isolates the full shank of the fastener. This design helps reduce vibration transfer, wear, and galvanic corrosion in mixed material assemblies.
The M6 range is widely used in equipment housings, electrical panels, automotive applications, machinery assemblies, and fabricated structures where larger fasteners require controlled spacing and non-conductive separation.
Multiple lengths are available to suit varying panel thicknesses and stand-off requirements.

❓ FAQs
What are M6 nylon shoulder washers used for?
They are used to insulate and space M6 fasteners in panel mounting, structural assemblies, and electrical installations.
Do these isolate the entire bolt or just the head?
The shoulder section isolates the fastener shaft within the hole, providing full separation.
Are these suitable for machinery applications?
Yes. M6 shoulder washers are commonly used in machinery housings and fabricated structures to reduce contact and vibration.
How do I select the correct M6 length?
Choose a length that matches your panel thickness or the required stand-off spacing in your assembly.
