Stainless steel hex socket bolt (cap bolt) with nylon lock processing.
This is a hexagon socket bolt with a Nylok treatment applied to the threaded part. Nylok creates a strong friction joint on the threaded part due to the elastic rebound force of the special nylon that is adhered to it, providing a permanent locking function against vibrations and impacts. It exhibits exceptional locking effectiveness in areas with frequent repeated use. Nylok is a registered trademark of Nylok LLC. What is Nylok: Nylok is a reliable locking treatment technology that permanently adheres special nylon to the threaded part. The principle of Nylok's locking mechanism is that when the screw is tightened, the elastic rebound force of the adhered special nylon generates a strong friction joint across the entire threaded part on the opposite side of the processed area, demonstrating a permanent locking function against vibrations and impacts. It shows outstanding locking effectiveness in areas with frequent repeated use. This offers advantages not found in locking nuts that deform the threaded part or in products that use adhesive for locking. This product complies with EU-RoHS standards.

![[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.
