Metric Ultra-Precision Lead Screws and Nuts
 |  |
Style C |
Operating with less backlash (play) than Metric Precision Acme Lead Screws and Nuts, these provide increased nut life and more reliable movement in automated systems. Also known as single-start and self-locking lead screws and nuts, they have a single thread that runs the length of the screw. The nut travels only when the screw turns, so your system won't unexpectedly move when the lead screw is at rest. To ensure compatibility, select components that have the same thread size, thread type, thread size, thread pitch, and number of thread starts.

Oversized Hardened Multipurpose M2 High-Speed Tool Steel Rods
 |
Also known as reamer blanks, these rods have an oversized diameter that allows for finishing to your exact requirements. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Tight-Tolerance Water-Hardening W1 Tool Steel Rods
|
Ready for turning in your lathe, these rods are precision ground and held to strict diameter and straightness tolerances. Also known as drill rod. With far less alloy content than other tool steel, W1 is the most machinable we offer. These rods are often used to make hammers, files, and reamers—tools that don't require the dimensional stability of A2 or O1. These rods are also decarb-free, which means any surface flaws created during the manufacturing process have been removed. This makes them even more machinable and leads to better results from heat treating or finishing. Heat treat the surface for extra wear resistance. Or, quench this steel in water to boost its hardness and strength, giving it a sharper, more durable edge for small tools.

Undersized Hardened Multipurpose M2 High-Speed Tool Steel Rods

These rods, also known as drill blanks, have an undersized diameter for machining your own drill bits. They're hardened for increased abrasion and impact resistance. M2 tool steel offers a nice balance of wear resistance and machinability. It has a high molybdenum content, which allows it to maintain sharp cutting edges even at elevated temperatures.

Tight-Tolerance Oil-Hardening O1 Tool Steel Rods
|
Ready for turning in a lathe, these rods are precision ground to a tight diameter tolerance. They’re also known as drill rod. Often used for dies, punches, and gauges, O1 tool steel is an oil-hardening material that resists wear and abrasion. It can also be surface hardened with heat treating for added wear resistance.
