Key Features & Benefits at a Glance
- Precise Motion Control: Delivers consistent 0.125" travel per turn for reliable positioning in automated systems.
- High Load Capacity: ASTM Grade B7 alloy steel construction provides exceptional 125,000 psi tensile strength for demanding applications.
- Superior Wear Resistance: Rockwell C35 hardness ensures extended service life under continuous operation.
- Left-Hand Threading Advantage: Enables reverse-motion applications where standard right-hand threads are unsuitable.
- Class 2G Thread Fit: Maintains optimal clearance for smooth operation while preventing backlash in precision assemblies.
- Full Thread Engagement: Maximizes load distribution across the entire 6-foot length for enhanced stability.
- Regulatory Compliance: Meets RoHS 3 and REACH environmental standards for safe industrial use.
Professional Applications & Engineering Value
This 3/8-8 Left Hand ACME lead screw solves critical engineering challenges in precision motion systems where reverse-direction operation and high load capacity are essential. The ASTM A193 Grade B7 alloy steel construction combined with Rockwell C35 hardness provides exceptional resistance to wear and deformation in continuous-cycle machinery. The fully threaded Acme profile with Class 2G fit ensures smooth, predictable movement in CNC equipment, lifting mechanisms, and industrial automation where positional accuracy is paramount. The left-hand thread direction offers unique solutions for applications requiring counter-rotational movement, while the single-start design maintains consistent 0.125" travel per revolution for precise control in manufacturing and material handling systems.
Specification Summary & Compliance
Manufactured to ASTM A193 specifications with Class 2G thread fit tolerances for inch-system applications. The Acme thread form (3/8-8) features single-start configuration with left-hand direction. Compliant with RoHS 3 (2015/863/EU) and REACH (EC 1907/2006) environmental standards, ensuring safe industrial deployment. Mechanical properties include 125,000 psi tensile strength and Rockwell C35 hardness per ASTM Grade B7 requirements.
