Tight-Tolerance Ultra-Machinable 12L14 Carbon Steel Rods

- Yield Strength: 65,000 psi
- Hardness: Rockwell B80 (Medium)
- Heat Treatable: Yes
- Max. Hardness After Heat Treatment: Rockwell C65
- Specifications Met: ASTM A108
Ready for turning in a lathe, these rods are precision ground and held to a strict straightness tolerance. The lead additive acts as a lubricant, which allows 12L14 carbon steel to withstand very fast machining. It's used to fabricate a wide variety of machine parts.

Rotary Shafts

Combine these general purpose drive shafts with gears, sprockets, and bearings to transmit rotary motion. All are precision ground to meet tight diameter and straightness tolerances.
Steel shafts are generally stronger than stainless steel shafts but not as corrosion resistant. 12L14 carbon steel shafts have a lead additive that makes them easier to machine than any other rotary shaft but also more prone to wear. Shafts with chamfered edges have their edges ground to reduce damage to bearings, housings, and other components during installation.

Undersized Dowel Pins

Slip these pins in and out during maintenance or prototyping—they’re undersized to make alignment easier. Unlike standard pins, which fit tightly inside holes, these are designed to give you some wiggle room. Chamfered ends make them easier to insert. The breaking strength listed is double shear, which is the amount of force required to break a pin into three pieces.
Steel pins are very strong. They are best for dry environments.
All metric pins meet ISO 2338-h8, which means they adhere to international standards for dimensions and tolerances.

Clamping Acme Lead Screw Collars

Thread these one-piece collars onto an Acme lead screw to separate and position components, or use them as an end stop to limit travel. Tighten the clamping screw to secure.
To ensure compatibility, please select a collar that has the same thread type, direction, and size as your lead screw.
Black-oxide carbon steel collars have mild corrosion resistance.
