maierke Crush Washer Oil Drain Plug Kit, 1160PCS M6–M24 Copper & Aluminum Assortment with Labeled Organizer

maierke 1160PCS Crush Washer Oil Drain Plug assortment is a comprehensive set of copper and aluminum sealing washers sized M6–M24 for reliable oil drain plug sealing, pressure distribution, and leak prevention in automotive and mechanical applications.

This kit gathers 1,160 crush washers in 18 metric sizes, split between durable copper and lightweight aluminum, and ships in a labeled plastic organizer for quick identification. The washers are intended for use anywhere a metal sealing washer improves the connection between fasteners — from engine oil drain plugs to hydraulic fittings. The mix of materials gives you options for different metal mating surfaces, temperatures and pressure conditions without having to buy single-size packs.

Which sizes are included and how many of each material?

The set covers common drain plug and banjo bolt sizes from M6 through M24, arranged across 18 size variations to fit most passenger cars, light trucks and many industrial fittings. Counting both alloys, the kit totals 1,160 pieces for extended workshop use and multiple service intervals.

• 18 metric sizes: M6, M8, M10, M12, M14, M16, M18, M20, M22, M24 (each in copper and aluminum variants)
• 489 copper washers for high-sealing strength on soft or tapered seats
• 671 aluminum washers for corrosion resistance and lighter-duty seals
• Clear quantity labeling on the organizer for fast selection

How do copper and aluminum crush washers differ and when should I use each?

Copper washers are softer and conform well to irregular or aged mating surfaces, improving the seal under moderate torque. Aluminum washers resist corrosion and weigh less, making them a practical choice for systems where galvanic compatibility or lower cost is prioritized.

• Copper: better conformity and long-lasting sealing on steel or iron mating parts
• Aluminum: corrosion resistance and suitable for aluminum housings or where metal compatibility matters
• Swap materials to avoid galvanic reaction depending on the drain plug and housing metals
• Both types crush to form a tight gasket under proper torque — replace each time the plug is removed

What applications will this crush washer kit cover in a garage or workshop?

This assortment is built to support routine maintenance and repairs across automotive, marine, and light industrial contexts. Typical uses include oil drain plugs, hydraulic fittings, banjo bolts, and other threaded joints where a thin metal seal prevents fluid leakage.

• Engine oil drain plugs on cars, motorcycles and light trucks
• Hydraulic and brake line banjo bolts where a metal seal is standard
• Marine and electrical connections needing corrosion-resistant options
• Household appliances and commercial equipment with threaded fluid connections

How is the kit packaged for storage and quick selection?

The washers arrive neatly organized in a portable, transparent plastic box with printed size labels so you can find the correct washer quickly. The compact organizer keeps different materials separated to avoid mix-ups during service.

• Sturdy plastic compartment box with removable trays for portability
• Printed labels for each size to speed part selection during maintenance
• Compact footprint fits tool chests or workbench drawers
• Refillable and reusable box for long-term shop storage

Who is this for: The maierke 1160PCS crush washer kit is aimed at professional mechanics, home DIYers who perform their own oil changes, fleet maintenance teams, and small commercial shops needing a broad range of metric sealing washers on hand. If you service multiple vehicle models or work across automotive and hydraulic systems, this kit reduces downtime and prevents improper sealing by providing the right size and material at the bench.
