S-91808A019 3/8"-10 Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• High-strength performance with Grade 2 carbon steel construction offering 64,000 psi tensile strength and Rockwell B85 hardness for reliable load-bearing in demanding environments.
• Precise left-hand thread engagement with Class 2G thread fit ensures smooth, backlash-resistant motion control in reverse-threading applications.
• Consistent 0.1" travel per turn delivers predictable linear movement, ideal for fine-adjustment mechanisms and positioning systems.
• Durable Acme thread form provides excellent wear resistance and efficient power transmission for long service life in industrial machinery.
• Standard hex nut design allows for easy installation and removal with common tools, reducing assembly time and maintenance costs.
• Full regulatory compliance with RoHS 3 and REACH standards ensures environmental safety and global market acceptance.
• Optimized for left-hand lead screw systems to prevent unintended loosening in counter-clockwise rotating applications.

Professional Applications & Engineering Value

This 3/8"-10 left hand Acme hex nut solves critical engineering challenges in motion control systems where reverse threading prevents accidental disengagement. Manufactured from Grade 2 carbon steel, it withstands continuous operational stresses in industrial automation, clamping fixtures, and precision adjustment mechanisms. The Class 2G thread fit maintains consistent performance under vibration while the Acme thread type offers superior wear characteristics compared to standard V-threads. With 0.1" travel per turn, it provides exact positional control in manufacturing equipment, medical devices, and transportation systems requiring left-hand threading reliability. The combination of 64,000 psi tensile strength and Rockwell B85 hardness ensures durability in high-cycle applications where component failure is not an option.

Specification Summary & Compliance
