Lead Screws
Tips & Advice to help you make your decision on Lead Screws
Lead Screws are not screws made of the heavy metal known as lead but instead, the term is used in the sense of leading, as Lead Screws are screws used to create a mechanical advantage, or lead. They typically convert the turning motion into linear motion. For example, a lead screw may be used to transfer turning motion into pressure.
The most common example of a lead screw is found in some car jacks. Most car jacks use a lever that translates motion, but some will use a rotational mechanism that converts turning motion into lifting energy. In industry, mechanically driven and manual presses will use a lead screw to allow the operator to create high pressure easily. A familiar application of lead screw technology is the vice. Most do-it-yourselfers have used a vice to hold items in place or together, especially when gluing. The turning of the screw creates pressure, and the threads of the screw hold that pressure until released.
There are three main types of these universal mechanical devices, based on the thread type. These include the Square thread, Acme thread, and buttress thread types. There are pages of formulas used to calculate the energy, friction, and operational limits.

Lead Screws
Find inch and metric lead screws, plus ball lead screws, for your businessBy Kristina Seleshanko Lead screws are used specifically for machinery that translates rotational motion to linear motion. They are considered 25% to 70% efficient and are quiet and vibration-free, making them ideal for equipment found in medical labs, desktop CD/DVD duplication devices and similar places. Ball lead screws are more efficient (usually about 90%), but also more costly. They are especially suited for situations that require high precision and smooth motion. Both types of screws must usually be well lubricated.
Lead screws and ball lead screws both come in a wide variety of sizes. Some are measured in inches, while others use the metric system. In this guide, you will discover sources for:
1. Metric lead screw products,
2. Lead screws in inches,
3. And ball lead screws.
Search out industrial lead screws in metric units
All types of lead screws come in metric measurements, including double lead screw products, segmented lead screws, linear lead screw items and CNC lead screw products. Most lead screw manufacturers and distributors carry most of these types of lead screws.
Try: Thread-Craft offers a variety of metric lead screws and assemblies for commercial needs. Keystone Threaded Products provides high strength metric lead screws for manufacturing. Universal Thread Grinding Company sells high quality metric lead screws for businesses.
Find lead screws in inches
All types of lead screws are usually available in inches. Additionally, many lead screw manufacturers and distributors provide conversion information for lead screws that easily translate from metric to inches.
Try: Nook Industries carries standard lead screws in inches. Danaher Motion offers a wide variety of industrial lead screws in inches. Roton Products offers a good selection of lead screws sold in inches to businesses.
Discover ball lead screws
Ball screws (also called ball bearing lead screws) have a train of ball bearings riding between the lead screw and the nut. The screw itself is rounded to conform to the balls. Distributors who sell traditional lead screws often also carry ball screws, but they're considered something of a speciality. Many sources also provide custom lead screw design, or do repairs on existing ball lead screws.
Try: Emcor specializes in ball lead screw manufacturing for shorter production runs and individual assembles. Lead Screws International creates ball screws; they also provide ball lead screw repairs. Techno offers lead ball screws in both metric and inches for business needs.
- Lead screws and ball lead screws are the workhorses of modern machinery. However, you must carefully consider load requirements when choosing these types of screws. Experts say that many times, applications are either over-engineered (leading to overly expensive screws) or under-engineered (leading to screw failure).
