boeray Woodruff Key Kit 164pcs — 17 Metric Sizes Carbon Steel Half-Moon Keys with Labeled Case

boeray 164Pcs Woodruff Key Kit is a complete set of carbon-steel half-moon keys in 17 metric sizes, supplied in a labeled storage case for fast selection and reliable shaft-to-hub connections.

This kit gathers a broad range of precision-machined Woodruff keys designed for pulleys, gears, sprockets and other keyed hub attachments. Crafted from carbon steel, each half-moon key balances wear resistance and dimensional consistency so you can perform maintenance, modifications or prototype builds without frequent restocking. The set’s clear plastic organizer keeps sizes visible and sorted, reducing downtime when you need the right thickness and length.

Which sizes are included and how many pieces will I have on hand?

The kit contains 164 individual Woodruff keys spanning 17 metric sizes, covering a wide spectrum of thicknesses and lengths so you’re prepared for common repair and assembly tasks.

• 17 distinct diameters and thicknesses: thickness 2mm–10mm, lengths 10mm–32mm, heights 3.6mm–13mm.
• 164 pieces total — plenty of duplicates for repeat jobs or wear replacement.
• Small sizes grouped and bagged to avoid confusion during selection.

How accurate and durable are these carbon-steel half-moon keys?

Each key is produced using precision machining for consistent geometry and fit, minimizing play between shaft and hub. Carbon steel construction gives a balance of strength and abrasion resistance for general mechanical use.

• High-precision machining ensures repeatable dimensions and reliable seating in keyways.
• Carbon steel offers improved wear resistance compared with softer alloys.
• Low coefficient of friction reduces binding during assembly and operation.

How does the storage case help on the job or in the workshop?

The kit’s sturdy plastic case is designed for organized storage and quick retrieval, which saves time especially when working across multiple machines or projects.

• Clear-lidded case with labeled compartments so sizes are visible at a glance.
• Keys stored left-to-right by size for intuitive selection and inventory control.
• Removable small-size bagging prevents tiny pieces from scattering and getting mixed up.

Is installing Woodruff keys difficult, and what applications are they best for?

Installation is straightforward: keys seat into the shaft’s semi-circular pocket and the mating hub slides over, locking rotational alignment. They’re ideal for pulleys, gears, timing components, and light-to-medium duty drive assemblies.

• Simple drop-in placement into machined shaft keyways for fast assembly.
• Commonly used in automotive, small engines, machine tools, and DIY mechanical repairs.
• Great for adjustments, replacements, and experimental builds where multiple sizes are tested.

Who is this for: hobbyists, mechanics, maintenance technicians and engineers who need a practical assortment of Woodruff keys for repairs, prototyping, and equipment upkeep. If you work on pulleys, gears, or keyed shaft assemblies and want a reliable, neatly organized selection of metric half-moon keys without repeated trips to the hardware store, this boeray kit offers the sizes and durability required for regular shop use.
