JM Hardware® Custom Stainless steel Screw
Custom Special Screws - Any Material, Any Finish, ISO 9001
Custom Special Screws — any material, any finish, made to order under ISO 9001 quality management. We manufacture bespoke heads, threads, lengths and tamper-proof designs to exact tolerances with full traceability and fast prototyping or volume production.
Usage scenarios:
- Precision electronics and medical devices that need corrosion‑resistant, fine‑thread screws in stainless steel or titanium with exact dimensions.
- Automotive and aerospace assemblies that require high‑strength alloy screws with protective coatings and certified lot documentation.
- Outdoor, marine and public‑facing fixtures or furniture that demand custom finishes (anodized, galvanized, powder coat) for corrosion protection, appearance and security.

Product Introduction
At JM Hardware®, we take pride in offering custom bolt solutions tailored to your specific needs. Custom bolts are a versatile fastening solution designed to meet unique project requirements, offering flexibility in material selection, surface finish, and functionality.
Material and Surface Finish:
Custom bolts can be manufactured from a variety of materials, including stainless steel, carbon steel, alloy steel, brass, and aluminum, among others. The choice of material depends on factors such as environmental conditions, load requirements, and corrosion resistance. Additionally, custom bolts can be finished with coatings such as zinc plating, galvanization, black oxide, or powder coating to enhance durability and appearance.
Functionality:
Custom bolts serve a multitude of purposes across various industries and applications. Whether you need structural bolts for heavy-duty construction projects, precision bolts for machinery assembly, or corrosion-resistant bolts for marine environments, we can tailor the design to meet your specific requirements. From standard hex bolts to specialized flange bolts, we offer a wide range of options to suit your needs.

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:

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.

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.

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.

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.

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.
