Frequently Asked Questions
What types of custom machine screws do you offer?
We provide a wide range of custom machine screws including various head types and drive styles, manufactured according to DIN, ISO, JIS, and AISI standards or specific customer drawings.
Which materials are best for corrosion resistance?
For excellent corrosion resistance, we recommend 304 or 316 Stainless Steel (304SS/316SS). 316SS is particularly effective in marine or highly corrosive chemical environments.
What size ranges are available for customization?
Our standard production range covers sizes from M3 to M20. However, we can evaluate specific requirements for sizes outside this range based on your project needs.
Can you manufacture screws to non-standard specifications?
Yes, customization is our specialty. We can produce machine screws with unique dimensions, thread pitches, and materials that go beyond standard international specifications.
Are carbon steel options available with surface treatments?
Absolutely. Our carbon steel machine screws can be finished with various coatings such as zinc plating, black oxide, or nickel plating to improve durability and appearance.
How do I ensure the screw fits my application?
We recommend verifying the required thread size (M3-M20), the material grade (304SS/316SS/Carbon Steel), and the specific standard (DIN/ISO/JIS) before ordering.
