Product Description

Heavy-Duty Threaded Fasteners made from high-grade 304 Stainless Steel are engineered for maximum durability and precision. These non-standard fasteners are ideal for applications where standard components fall short in terms of geometry, strength, or corrosion resistance.

Key Applications

High-Corrosion Environments: Chemical processing, marine hardware, and food machinery.
Precision Machinery: Custom screws and pins for robotic joints and automated assemblies.
Medical & Laboratory: Specialized adjustment knobs and housing screws for non-implantable devices.
Aerospace & Defense: Ground support brackets and panel fasteners requiring environmental resistance.
Electronics: Standoffs and captive screws for cleanroom or corrosive environments.

Frequently Asked Questions

1. What materials do you primarily use for these fasteners?

We mainly use AISI 304 Stainless Steel, but we also process copper, aluminum alloy, and other grades of stainless steel based on custom requirements.

2. Can you provide custom thread pitches or head designs?

Yes, we specialize in non-standard components. We can produce ACME, trapezoidal, and custom pitch threads, as well as unique head geometries through CNC milling.

3. What is the standard dimensional tolerance for your parts?

Our standard tolerance is ±0.05 mm on major diameters. For critical fits, we can achieve high precision up to ±0.02 mm.

4. Do you offer surface finishing services?

Yes, we provide standard machined finishes, deburring, passivation (ASTM A967), electropolishing, bead blasting, and vibratory finishing.

5. Are your products suitable for medical applications?

Absolutely. We are ISO 13485 certified, and our precision parts are widely used in medical device housings, laboratory equipment, and other non-implantable medical tools.

6. How is the quality of the material verified?

We provide Mill Test Certificates confirming the material grade and composition for full traceability of all products.
