Choose by failure mode first: loosening, corrosion, weight, load, or water ingress
This index routes engineering and purchasing teams to the right fastener technology before they choose a SKU. Each solution connects the problem, safe applications, proof points, and BOM review path.
Anti-Loose Bicycle Fasteners
Nord-Lock washers, pre-coated thread adhesive, nylon patch, and prevailing torque lock nuts.
- Best for MTB pivots, disc brake mounts, folding hinges, motor mounts, and drivetrain hardware.
- Proof points: locking method selection, torque documentation, Junker-test-oriented specification.
Anti-Corrosion Bicycle Bolts
Dacromet, Zn-Ni, DLC, TiN, and A4-70 stainless options for wet, coastal, and all-weather riding.
- Best for pivots, brake mounts, bottle bosses, rack/fender mounts, and exposed e-bike hardware.
- Proof points: 400-1000+ hour salt spray targets, coating matrix, RoHS/REACH support.
Lightweight Titanium and Aluminum Bolts
Ti-6Al-4V Grade 5 titanium, 7075-T6 aluminum, and optimized steel for safe weight reduction.
- Best for cockpit, bottle cage, saddle, non-structural frame, and race-focused BOM positions.
- Proof points: application limits, material matrix, weight-saving examples, unsafe substitution warnings.
High-Strength Bicycle Bolts
12.9 alloy steel, 17-4PH stainless, 4130 chromoly, and Ti-6Al-4V for structural and high-torque joints.
- Best for e-bike motor mounts, suspension pivots, axles, shock mounts, and brake load paths.
- Proof points: tensile class, fatigue consideration, corrosion tradeoff, torque traceability.
Waterproof Sealed Fasteners
O-ring sealed heads, captive sealing washers, pre-applied sealant, and stainless substrates.
- Best for e-bike battery compartments, motor covers, controller housings, and cable gland screws.
- Proof points: sealing stack, vibration after sealing, corrosion-resistant materials.
