HOLMOL Flat Penny Washers 250 pcs — Stainless Steel

This set of flat penny washers offers a versatile assortment for general maintenance, furniture assembly and light engineering tasks, helping to distribute load and reduce wear around screw and bolt heads. The pack concentrates on reliability for workshop, garage and household jobs, offering corrosion resistance and consistent dimensions for repeated use. 😊

Key Points

These washers come in a mixed kit of 15 sizes to cover common metric bolts and screws, which simplifies keeping the correct washer to hand during repairs or installations. The smooth finish reduces scratching on mating surfaces and the flat profile works well under countersunk and raised heads alike. They are suitable for a wide range of projects from carpentry to automotive trim where basic load distribution and protection of surfaces are required.

The product uses stainless material that resists rust in normal indoor conditions, according to the manufacturer. This makes the set practical for occasional exterior use in sheltered locations, however continuous exposure to marine environments may still require specialised fasteners. ⚙️

Usage Recommendations

For reliable joints place a washer under the bolt or nut head before tightening to improve load distribution and reduce the chance of embedment into soft materials. When working with moving machines, using a washer can help limit loosening caused by vibration and oscillation. For sealing tasks, combine the flat washers with appropriate gaskets or seals to avoid fluid seepage, since flat metal washers alone offer limited sealing capability.

Keep the sizes organised in a small compartment box to speed up selection during repeat jobs and to prevent loss of small items. Consider pairing the stainless washers with matched stainless fasteners for consistent corrosion performance, particularly in outdoor or damp environments.
