John Deere Round Hole Washer - Z81151 is an annular, flat washer designed to sit beneath a bolt head, rivet head, or nut in fastener assemblies. It distributes pressure, establishes a predefined spacing, or helps achieve a controlled clamp preload. The available thickness range covers 0.77 mm up to 9.53 mm (inclusive).

Key Features

• Material options include metal, felt, fiber, or other suitable materials to match application needs and environmental conditions.
• Annular, flat geometry provides a uniform contact surface for even load distribution across the contact area.
• Defined thickness range from 0.77 mm to 9.53 mm (inclusive) enables selecting the appropriate spacer or preload level for specific assemblies.
• Functions under bolt head or nut to prevent surface embedding, distribute pressure, and maintain consistent clearance.
• Simple, compatible form factor for standard round-hole fastener configurations.

Product Details

• Model: Z81151
• Form factor: annular (ring), flat washer
• Material options: metal, felt, fiber, or other suitable materials
• Primary purpose: distribute pressure, create predefined pressure or space, and support reliable clamp preload
• Thickness availability: > 0.77 mm and ≤ 9.53 mm
• Notes: Outer diameter and inner hole specifications are not provided in the available data; design is intended for standard fastener assemblies with round holes

Compatibility

• Best suited for standard bolt and nut assemblies that require load distribution under the head or nut.
• Applicable to round-hole fastener configurations where a flat, annular washer with the specified thickness range is appropriate.
• Thickness selection supports varying spacings and preload levels to accommodate tolerances and material softness at contact surfaces.
