Key Features & Benefits at a Glance
- Exceptional load-bearing capacity with 125,000 psi tensile strength for reliable performance in demanding industrial applications.
- Superior wear resistance and durability thanks to the ASTM Grade B7 alloy steel construction and Rockwell C35 hardness.
- Precise and predictable linear motion with a 0.2" travel distance per turn and Class 2G thread fit for accurate positioning.
- Reliable reverse or counter-clockwise motion control enabled by the left-hand Acme thread design.
- Full-length engagement capability as a fully threaded screw provides consistent force transmission along the entire 3-foot length.
- Guaranteed material quality and consistency through compliance with the ASTM A193 specification for high-strength fasteners.
- Safe for use in regulated environments with full compliance to RoHS 3 and REACH environmental standards.
Professional Applications & Engineering Value
This 1"-5 Left Hand Acme Lead Screw is engineered to solve critical challenges in precision motion control systems. The ASTM Grade B7 alloy steel construction provides the high tensile strength and hardness required to withstand heavy loads and repetitive use without deformation, a common failure point in less robust components. The left-hand Acme threading is specifically designed for applications requiring reverse-threading operations or where standard right-hand threads could loosen under specific directional forces. Combined with the Class 2G thread fit, this lead screw delivers the precise alignment and minimal backlash needed for accurate positioning in machinery such as CNC equipment, valve actuators, and heavy-duty linear actuators. Its fully threaded, 3-foot length offers maximum flexibility for custom machine designs requiring long-travel movement.
Specification Summary & Compliance
This Acme lead screw features a 1"-5 thread size with a Class 2G thread fit per standard inch-based tolerances, ensuring proper mating with corresponding nuts. It is manufactured from ASTM Grade B7 alloy steel as defined by the ASTM A193 specification. The product is fully compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental regulations, confirming it is free of restricted hazardous substances.
