255PCS Grease Fittings Assortment SAE & Metric Kit - Durable

In this review the 255PCS Grease Fittings Assortment is evaluated as a hands-on toolkit for anyone who maintains machinery. The reviewer found the single biggest reason to buy is the combination of durable galvanized steel fittings and a reinforced storage box that keeps dozens of sizes and angles organized and ready for service work. For DIY mechanics and professionals who need a broad selection of straight, 45 and 90 degree zerk fittings in both SAE and metric threads, this kit removes the guesswork and minimizes downtime.

Key Features

• Durable galvanized steel: Each fitting is made from structural steel with galvanized plating to resist corrosion and extend service life in industrial environments.
• Various standard sizes: The assortment includes 1/4' and 1/8' plus M6, M8 and M10 sizes so users can match common SAE and metric lubrication points without chasing parts.
• Straight and angled fittings: Straight, 45 and 90 degree zerk fittings let you reach tight or awkward grease nipples without disassembly.
• Extra accessories: The included wrenches in multiple sizes make installation and removal easier and reduce the risk of rounding fittings during service.
• Reinforced storage box: A stronger box than typical plastic organizers keeps the fittings sorted, portable, and protected from loss or contamination.
• Wide compatibility: The kit suits automotive, tractor, truck, excavator and bearing lubrication tasks across hobby and industrial use.

Who It's For

The kit is aimed at hands-on mechanics, fleet maintenance crews, and serious DIYers who service vehicles, agricultural equipment or workshop machinery and need a comprehensive set of fittings to cover both SAE and metric threads. The variety of angles and sizes is particularly useful for shops that encounter varied equipment and want to avoid multiple single-size purchases.

Those who should look elsewhere are users who only need a couple of replacement fittings infrequently or customers seeking stainless steel fittings for highly corrosive environments; this kit emphasizes galvanized structural steel rather than specialty stainless alloys.

Pros & Cons

Pros

• Comprehensive selection of SAE and metric sizes reduces trips to the parts store and solves mixed-thread maintenance jobs.
• Galvanized finish provides sensible rust resistance for typical workshop and field use.
• Reinforced storage box and included wrenches make the set practical and portable for on-site work.

Cons

• Galvanized steel is not a substitute for stainless in extremely corrosive or marine environments.
• The kit may be overkill for users who only need one or two fittings occasionally.

Frequently Asked Questions

Are these fittings suitable for heavy machinery?
Yes, the fittings cover common threads and angles used on tractors, trucks and excavators, making them suitable for routine lubrication tasks on heavy equipment.

Do the fittings resist rust?
The fittings have galvanized plating for improved rust resistance in typical workshop and field conditions, but not the same corrosion resistance as stainless steel.

Are the wrenches included adequate?
The kit includes several wrenches (approximate sizes 7-11mm) that are sufficient for installation and removal of the supplied fittings.
