Product Introduction


Hex Flange Screws (also called Flange Bolts) incorporate a large bearing face (flange) into a one piece head design. The large bearing area under the head of this design provides additional benefits for assemblies over standard hex head cap screws:

Large bearing area under the head distributes clamp load over a larger area to resist fatigue loads. Minimizes indentation of the head into the material being bolted together to prevent loosening. Increases the heads resistance to rotation to prevent loosening in high vibration applications. Eliminates the need for a flat washer.

Hex Flange Screws are commonly called Frame Bolts because of their popularity in the trucking industry for use on assembly of truck frame rails. Hex Flange Screws are also used on pipe flange applications because the larger bearing area under the head helps ensure that the gasket is uniformly compressed to eliminate leaks. Hex Flange Screw can be used in any assembly that is currently using a hex cap screw and washer to eliminate the washer.

Quality Control


JM Hardware conducts product quality control in strict accordance with ISO 9001 standards to ensure that our products meet high quality standards. Below are our five quality control steps:

1
1
Incoming material control
We carry out strict incoming material control by conducting dimensional tests on each batch of raw materials and checking the raw material reports from the steel mills. This ensures that the raw materials we use are within specification and provide a reliable basis for production.
1
1
First part control
After the mold assembly is completed, we conduct a thorough inspection of the first production part and make detailed records. Only qualified first parts can be released to start mass production. This step ensures that the quality of the product meets the standard at the beginning.
1
1
Self-inspection by workers during mass production
In the mass production process, we require the workers of each machine to carry out self-inspection every hour. If any substandard product is found, we will immediately pick or scrap the production within this hour until the problem is solved and meets the standard of conformity, and then we can continue the production. This self-inspection mechanism helps to find and solve problems in time during the production process.
1
1
QC inspection during mass production
In addition, every two hours, the quality inspection personnel will carry out random inspection on the products of each machine. Only qualified products can continue to flow into the next production stage. If non-conforming products are found, we will take the same selection or scrapping measures and ensure that the problem is properly handled. This helps provide additional quality assurance.
1
1
Finished product control
Finally, after each batch of finished product is made, we conduct random inspections in proportion to the order. Qualified products will be packaged and put into storage, while unqualified products will be returned for further analysis and rectification. We insist on ensuring that the quality of our products meets high standards so that we can provide reliable products to our customers.

Non-conforming goods management
According to the process of JMhardware's non-conforming products handling, pick or scrap. And the problem of rectification and tracking reasons to ensure that non-conforming products will not flow into the market.

These quality control measures constitute JM Hardware's quality management system, and we are constantly striving to improve the quality of our products and are committed to meeting the needs of our customers. We believe that quality control is the key to our success.
