Value Collection A997411 M16 Fender Flat Washer 25-pack

Product Description

The VALUE COLLECTION A997411 is a metric fender flat washer designed for use with M16 fasteners. Manufactured from steel with a zinc-plated finish, this washer features a 17mm inside diameter, a 50mm outside diameter, and a 3mm thickness. The large outer diameter relative to the bolt size is the defining characteristic of fender washers, distributing clamp load over a wider surface area to prevent pull-through in softer or thinner base materials. Each package contains 25 washers. This item is commonly installed by mechanical, plumbing, and structural tradespeople working with metric fastener assemblies.

Fender washers in this size range are used across a wide variety of commercial and industrial applications where M16 bolts or screws are specified. They are commonly found in equipment mounting, panel attachment, structural bracketing, and pipe support assemblies. The oversized OD makes them well suited for applications involving sheet metal, wood, or composite panels where standard washers would provide insufficient bearing surface. Sold in a pack of 25 to support small-batch job needs.

Key Features

• 17mm inside diameter fits M16 fasteners
• 50mm outside diameter provides wide load distribution
• 3mm thickness for solid bearing surface
• Steel construction with zinc-plated finish for corrosion resistance

Compatibility

Designed for use with M16 metric screws and bolts. Conforms to DIN 9021 and ISO 7093 standards, making these washers interchangeable with other metric fender washers manufactured to the same specifications.

Installation Notes

Installation does not require specialized tools beyond standard wrenches or sockets sized for the M16 fastener being used. Ensure the mating surface is clean and flat before seating the washer to maintain consistent clamp load. Zinc-plated washers are suitable for dry or mildly corrosive environments — consult project specifications if exposure to harsh chemicals or standing moisture is expected. Always torque fasteners to the value specified by the equipment manufacturer or applicable project drawings.
