320 PCS SAE & Metric Grease Fittings Kit - Full Zerk Assortment

Our review of this 320-piece grease fitting kit finds it best suited to mechanics and maintenance professionals who need a broad, ready-to-use selection of grease zerks for both SAE and metric equipment. The single biggest reason to consider this set is its comprehensive mix of fittings plus a sturdy, labeled storage case that keeps sizes organized and accessible, which saves time during recurring lubrication tasks. The kit's galvanized steel construction and included caps and wrenches make it a practical all-in-one solution for workshop and industrial use.

Key Features

• All-in-One Set: Includes 320 pieces across 15 common SAE and metric grease fitting types so you rarely need to source an extra size.
• Durable Material: Galvanized steel construction resists corrosion, rust and oxidation for long service life in harsh environments.
• Convenient Design: Straight, 45 and 90 degree heads connect quickly without disassembly for faster lubrication of hard-to-reach fittings.
• Sturdy Storage: The case has clear labels and thick partitions so each fitting size stays organized and is easy to find on the bench.
• Accessory Kit: Comes with 20 grease zerk caps and five 7-11mm wrenches so you have immediate tools for installation and protection of fittings.

Who It's For

This kit is aimed at automotive technicians, industrial maintenance crews and serious DIYers who deal with a mix of SAE and metric lubrication points and want a single case that covers most standard needs. The wide variety of angles and thread sizes is useful when machines have confined access or when working across multiple vehicle makes.

Casual users with only a couple of grease points might find the full 320-piece set excessive and should consider a smaller pack. Also, if someone requires specialty high-pressure or stainless fittings for corrosive chemicals, they should choose fittings specified for those conditions instead.
