S-95072A352 3/4"-8 x 1 1/4" Precision Acme Lead Screws and Nuts

Key Features & Benefits at a Glance

• Exceptional Load Handling: Supports up to 2800 lbs dynamic thrust load for demanding high-force applications.
• Precision Left-Hand Threading: 3/4"-8 Acme thread ensures reliable, non-standard motion control where reverse operation is required.
• Durable 360 Brass Construction: Offers excellent corrosion resistance and maintains integrity with Brinell 70 hardness.
• Accurate Class 2C Thread Fit: Provides consistent, smooth engagement with mating screws, reducing backlash and wear.
• Optimized Travel Efficiency: 0.125" travel per turn delivers predictable linear motion for precise positioning.
• Robust External Threading: 1"-18 UNS external threads allow secure integration into assemblies.
• Compact, Heavy-Duty Design: 1 1/4" length and 1.125" diameter balance space savings with strength.

Professional Applications & Engineering Value

This 3/4"-8 Acme left-hand thread brass nut is engineered to solve critical challenges in industrial systems requiring reverse or counter-rotational motion. Made from 360 Brass, it resists corrosion and galling, extending service life in harsh environments like packaging machinery, valve actuators, and precision positioning equipment. The Class 2C thread fit and Acme thread form ensure minimal play and reliable power transmission under high dynamic thrust loads up to 2800 lbs. Its left-hand thread direction is ideal for applications where standard right-hand threads could loosen, providing a secure solution for tandem screw systems or safety-critical assemblies. The combination of Brinell 70 hardness and precise 0.125" travel per turn makes it a dependable choice for engineers seeking durability and repeatable performance in precision lead screw setups.

Specification Summary & Compliance

This nut adheres to inch system standards with a Class 2C thread fit for Acme threads, ensuring dimensional accuracy and interchangeability. Key specifications include a 3/4"-8 Acme left-hand thread, external 1"-18 UNS thread, and compliance with industry-accepted manufacturing practices for precision Acme lead screws and nuts. The 360 Brass material and construction meet general industry requirements for mechanical components, though specific certifications like RoHS or ASME should be verified per application needs.
