Trapezoidal threaded rod 12 x 3 x 1000 mm No name PGT 12*100

Trapezoidal threaded rod 12 x 3 x 1000 mm is a single-piece metal rod designed with a trapezoidal thread profile for converting rotary motion to linear motion in mechanical assemblies. With a nominal diameter of 12 mm, thread pitch of 3 mm and overall length of 1000 mm, this rod is intended for use in jacks, lead-screw mechanisms, custom actuators and repair tasks where robust axial load capacity and reliable translation are required.

Advantages

The trapezoidal profile provides improved contact area and load distribution compared with standard V-threads, offering greater wear resistance and smoother linear travel under load. The one-piece metal construction ensures consistent alignment and stiffness along the full length, reducing the risk of bending or backlash in supported installations. The 3 mm pitch balances travel speed and mechanical advantage for many general-purpose motion applications.

Suitable for

• Linear actuators and lead-screw driven stages
• Mechanical jacks and lifting devices
• Machine repairs and retrofit projects
• DIY projects and custom motion assemblies

Key specifications

• Thread profile: trapezoidal
• Nominal diameter: 12 mm
• Thread pitch: 3 mm
• Overall length: 1000 mm
• Material: metal (single-piece rod)

How to use

Install the rod in a compatible nut or carriage designed for trapezoidal threads, ensuring correct engagement along the full thread length. Support the rod at suitable intervals or with bearings to prevent deflection during operation. When cutting or trimming to length, preserve the thread run-out by finishing the cut end and, if necessary, rethreading the tip. Use appropriate lubrication and torque settings for the intended load to reduce wear and improve efficiency.

Usage recommendations

For reliable performance, pair the rod with a matching trapezoidal nut or anti-backlash nut and secure support bearings at the ends. Apply periodic lubrication with suitable grease to minimize wear. Avoid excessive lateral loads and ensure correct alignment to maintain translation accuracy and prolong service life.
