No need for counterbore processing! Ideal for areas where you want to minimize the protrusion of the screw head or reduce weight.
The "Ultra Low Head CAP" is a hex socket bolt with an even lower head than a low head bolt. It is suitable for areas where you want to minimize the protrusion of the screw head or reduce weight. Since countersinking is not required, it allows for a reduction in work processes and time. We can also accommodate various additional processing requests as needed. 【Features】 ■ Head height is even lower compared to low head CAP ■ No countersinking required, minimizing head protrusion ■ Additional processing such as various surface treatments and anti-loosening treatments is also available *For more details, please refer to the related links or feel free to contact us.
![[Case Study] Cost Reduction through Changes in the Manufacturing Method of Mass-Produced Screws](https://image.mono.ipros.com/public/product/image/90e/2000999157/IPROS26112908317921160821.png?w=280&h=280)
A case where the manufacturing method was changed from cutting processing to forging processing, resulting in a 70% cost reduction in the customer's purchase price.
We would like to introduce a case where we proposed "reducing the manufacturing process and increasing production lots" to an industrial machinery manufacturer. The customer was purchasing low-head type special-shaped hexagon socket bolts M2 from an e-commerce site, but due to high unit prices and an increasing quantity needed, they expressed a desire to reduce costs. We proposed a change in the manufacturing method, which was adopted without any issues and was equivalent to or better than the conventional products, resulting in significant cost reductions. [Case Overview] ■ Issues - Costs had become excessively high - The shape was not particularly difficult to manufacture, despite being outside JIS standards ■ Requirements for Solving the Issues - Reduction of costly machining processes - Establishing a production lot that ensures stable lead times *For more details, please refer to the related links or feel free to contact us.
![[Case Study] Coating the Head of a Left-Hand Thread Hex Socket Bolt](https://image.mono.ipros.com/public/product/image/bbe/2000999175/IPROS61313075676963499293.png?w=280&h=280)
Production completed in time for the desired delivery date! A case of proposing alternatives for discontinued products from the manufacturer.
We would like to introduce a case where we proposed an alternative for a left-handed hex socket bolt that has been discontinued by the manufacturer and is no longer available in the market for a textile machinery manufacturer. The M3×7 uncoated hex socket bolt (left-handed) used in textile machinery was discontinued, and without finding an alternative product, the production line would come to a halt, impacting sales. We proposed machining the dimensions of the left-handed hex socket bolt and painting the head, allowing for the selection of right-handed and left-handed screws without changing the screw size, and we were able to deliver the product by the desired deadline. [Overview of the Issue] - The M3×7 uncoated hex socket bolt (left-handed) was used in textile machinery, but production by the manufacturer has ended, and it has been discontinued. - If an alternative product cannot be found, the production line will stop, affecting sales. *For more details, please refer to the related links or feel free to contact us.

Introducing the different uses of hexagon socket bolts in a blog format!
For bolts with hexagonal holes, we will consider the so-called standard hexagon socket bolts as the reference. Although it is slight, using hexagon socket button bolts with a larger head diameter can stabilize the seating surface, which is the contact area between the screw and the counterpart material, and alleviate the sinking (dimpling) into the counterpart material. However, it seems that button bolts are often used to create a neat appearance in the visible parts of the fastening section. *For more details, you can view the related links on the blog. Please feel free to contact us for more information.*
Improved reliability and workability by preventing loosening with high tightening force.
Hexagon socket bolts (caps) are generally used without being paired with nuts, so referring to them as screws is more accurate. However, since the name hexagon socket bolt has become widespread, they are also referred to as cap bolts. The applicable strength grades are 10.9 and 12.9. They are tightened with a hexagonal rod wrench (with a maximum length of 1,000 mm possible). *For urgent or emergency situations, or for technical inquiries, please contact us directly through our website.
