Washer Baks PW10 enlarged 10 mm, pack of 100, MPN 651044

Washer Baks PW10 enlarged 10 mm, pack of 100 is a flat metal washer with a 10 mm inner diameter designed to increase the bearing surface beneath bolt heads and nuts. Supplied in a pack of 100, this washer type is intended for situations where a larger contact area is needed to distribute load, reduce surface indentation and improve joint stability in general fastening, repair, assembly and construction tasks.

Advantages

The enlarged flat washer offers a wider contact area than standard washers, helping to spread clamping forces over a greater surface and reduce the risk of material deformation. Its uniform thickness ensures consistent load transfer and simple installation under bolts and screws with 10 mm shafts. Packaged in a quantity of 100, it provides a practical supply for small to medium projects and routine maintenance.

Suitable for

• Securing bolts and nuts in wood, metal and composite assemblies
• Distributing load on soft or thin materials to prevent pull-through
• General repair and maintenance tasks in workshops and on-site
• Construction and assembly jobs requiring a larger bearing surface

When it may not be suitable

This enlarged washer is not intended for use as a locking device; it does not provide anti-rotation or vibration-prevention features by itself. It may be unsuitable where specific corrosion resistance, hardness ratings or thread-sealing properties are required—choose a washer material or coating rated for the environmental and mechanical stresses of your application.

Key specifications

• Inner diameter: 10 mm
• Type: enlarged (oversized) flat washer
• Pack quantity: 100 pieces
• Typical use: load distribution under bolt heads and nuts
• Shape: flat, circular

How to use

Place the washer between the bolt head or nut and the workpiece so the 10 mm inner hole fits over the bolt shaft. Tighten the fastener to the required torque while ensuring the washer remains flat against the surface. For assemblies with softer materials, position the enlarged washer on the side needing protection to spread the load and reduce indentation. Use alongside appropriate thread lubrication or locking methods when required by the application.

What to consider before purchase

• Confirm the bolt or screw shaft diameter is 10 mm to ensure proper fit
• Check the washer material and any coating to match corrosion and strength requirements
• Ensure enlarged bearing surface dimensions are suitable for the workpiece to achieve intended load distribution

Usage recommendations

For best results, combine these enlarged flat washers with properly sized bolts and appropriate torques for the materials involved. When fastening into soft substrates, consider using multiple washers or backing plates to further increase bearing area.
