Custom and standard fasteners manufactured to AS9100D aerospace standards. From precision bolts and screws to complex studs, nuts, and specialty fasteners, we deliver components meeting ANSI, DIN, ISO, and military specifications with tight thread tolerances, controlled head dimensions, and complete material traceability for critical aerospace, defence, and industrial assembly applications.
Our precision CNC turning and machining capabilities deliver custom fasteners with exceptional accuracy when standard off-the-shelf components won't meet your requirements. Whether you need non-standard thread sizes, special head configurations, exotic materials, or unique lengths, we manufacture fasteners to exact specifications with tight thread tolerances and controlled dimensional accuracy.
From miniature aerospace fasteners to large industrial bolts, we work with a comprehensive range of materials including alloy steels, stainless steels, titanium, and specialty alloys. Complete heat treatment, thread rolling, and surface coating services ensure your fasteners meet the most demanding strength, corrosion resistance, and assembly requirements with full traceability and certification.

Common questions about custom fastener manufacturing
We have no strict minimum order quantity for custom fasteners. We can efficiently produce single prototypes for development work or production volumes in the thousands. Setup costs are distributed across the order, so larger quantities offer better per-piece pricing, but we're happy to support your requirements whether you need 10 pieces or 10,000.
Yes, we manufacture fasteners to military specifications (MS, NAS, AN) and aerospace standards. We can provide complete documentation including AS9102 First Article Inspection Reports, material certifications with full traceability, mechanical test data, and coating certifications. Our AS9100D certification ensures we meet aerospace quality requirements with proper documentation and control throughout manufacturing.
We routinely achieve 2A/2B thread class for general applications and 3A/3B for precision requirements. Metric threads are typically manufactured to 6g/6h tolerance class. Thread rolling produces superior strength and surface finish compared to cut threads. We verify all threads with calibrated plug/ring gauges and can provide thread inspection reports showing major diameter, minor diameter, and pitch diameter measurements.
Yes, we provide complete heat treatment services including through hardening, case hardening, and tempering to achieve specific strength grades (Grade 5, Grade 8, etc.). Surface treatments include zinc plating (clear, yellow, or black chromate), cadmium plating for aerospace, black oxide, passivation for stainless steel, and specialty coatings like PTFE or electroless nickel. All treatments include certifications and test documentation.
Yes, we can reverse-engineer replacement fasteners from samples. Send us the existing fastener and we'll measure thread pitch, diameter, length, head style, material, and any special features. We can then manufacture exact replacements or improved designs with better materials or coatings. For critical applications, we recommend providing original specifications if available to ensure proper strength grades and certifications.
Lead times vary based on complexity, quantity, material, and finishing requirements. Simple custom fasteners from stock materials typically take 2-3 weeks. Fasteners requiring special materials, heat treatment, or plating may take 3-4 weeks. Complex multi-diameter or specialty fasteners may require 4-6 weeks. High-volume production orders are quoted based on quantity. Rush services available for urgent requirements.
We accept PDF, DWG, DXF, STEP, IGES, and most common CAD formats. Even hand sketches with critical dimensions clearly marked are acceptable. At minimum, we need thread specification (M8x1.25, 1/4-20 UNC, etc.), length, head style, and material. If you don't have drawings, we can work with you to define the fastener specifications based on your application requirements.
Yes, all custom fasteners include material test reports (MTR) with full traceability to heat lot. For aerospace applications, we provide AS9102 First Article Inspection Reports, Certificate of Conformance (C of C), mechanical test data (tensile strength, proof load, hardness), coating certifications, and any additional testing required by your specifications. All documentation includes batch/lot traceability for complete accountability.
