FASTENINGS AND RELATED HARDWARE FOR AEROSAPCE MANUFACTURING

We offer a comprehensive range of MS (Military Standard) and NAS (National Aerospace Standard) fasteners engineered for use in high-reliability and regulated manufacturing environments. Our offering includes screws, bolts, nuts, washers, pins, and structural fasteners commonly specified in aerospace, defence, medical, semiconductor, and other critical industries.

Where required, fasteners can be supplied with full material and batch traceability, including certificates of conformity, material certifications, and supporting quality documentation to meet audit and compliance requirements.

Our MS and NAS fasteners are available across a broad range of inch and metric sizes, thread forms, head styles, and strength grades, and in materials such as alloy steel, stainless steel, corrosion-resistant steels, titanium, and other specialty alloys. In addition to standard parts, we can support custom sizes, materials, coatings, and special configurations for application-specific requirements, including high-temperature, corrosion-critical, and low-outgassing environments.

Whether your requirement is for prototype quantities, small-batch builds, or ongoing production supply, we provide the flexibility, technical support, and quality assurance needed to deliver dependable fastening solutions.
