Thread is ideal for Jacks,Vises(quick released) army and heavy lifting system, where force acts in one direction.There unsymetrical profile (one square and one slanted) provides heigher shear strenght, low frictionfor forward motion, very good load capacityfor axiel thrust which causes them perfect for lead screw in heavy duty machinery
APPLICATION OF THREAD;
1. SCREW JACKS & PRESSES:- Used for screw presses, heavy duty Jacks and vertical lifts.
2. LIFTING SYSTEM:- Spindle for mining lifts,and vertical lifts
3. MACHINE TOOLS:- Lead screw, power screw, collets in turning and milling operations.
4. MILITARY:- Used in breech blocks for artillary means to set the barrel head to breech block this thread is adopted for quick engagement.
5. OIL & GAS:- It provides sealed connection in tubings.
WHY USED THIS THREAD ?
HIGH UNIDIRECTIONAL LOAD:- The perpendicular force efficiently handleslarge force pushing in one direction.
STRENGHT:- Stronger than Acme thread due to its thicker base.
EFFICIENCY:- Combines good forward efficiency with ease of cutting.
ASYMMETRIC DESIGN:- Slanted flanks allows for smooth engagement,square flank carries the loads.
