A screw that promotes automation

Reduces loss cost of poor screw fastening to less than one-tenth

Based on the research conducted at an industrial equipment manufacturer that fastens 3.6 million screws of one type (pan-head screw M2.5) per year to investigate screw fastening error occurrence rate and its loss cost.
Comparison table
*Research result in FY2019
Cross-head-screw INTRTORQUE Effectiveness
Fastening error count including cam out, cross threaded, screw dropping, etc. (3.6 million screws/year) 500 0 Zero fastening error
Rework time (approx. 40 seconds/screw fastening) 5 hours
33 minutes		 0 minutes Zero rework hours
Labor cost for rework (1,800 yen/hour) Approx.10,000 yen 0 yen Zero rework labor cost
Number of bits (3.6 million/year) 360 bits 30 bits Reduced to 1/12
Bit cost (@\1,000/bit) 360,000 yen 30,000 yen -330,000 yen
