Selecting the right fastening solution is essential for safety, durability, and performance across military, aerospace, marine, and industrial applications. Whether you’re assembling complex subsystems or rugged outdoor platforms, Metric Bolt offers a range of engineered solutions designed to meet stringent requirements.
Core Fastening Categories
1. High‑Strength Bolts & Screws
Designed for high-load joints and structural connections—offered in alloy steel, stainless, titanium, and nickel alloys. Available with enhanced locking options and torque inserts for vibration resistance and preload stability.
2. Rivets & Structural Fasteners
Ideal for permanent, shear-critical applications. We provide blind rivets, solid rivets, and specialty rivets engineered for high fatigue life and reduced weight in aerospace and vehicle platforms.
3. Specialty Fastening Systems
Includes captive bolt assemblies, threaded inserts, and collar systems tailored for quick assembly, cleanliness, and integration into electronics enclosures, sensor arrays, or composite materials.
4. Coatings & Corrosion Control
Fastener finishes include zinc‑nickel, cadmium alternatives, anodizing, and PVD ceramics—selected to match environmental and regulatory needs while maintaining precise tolerances.

Fastening Solutions
| Solution Type | Material / Feature | Primary Applications |
|---|---|---|
| High‑Strength Bolts/Screws | Alloy steel, Ti‑6Al‑4V, Inconel with locking thread | Structural joints, armor, high-vibration zones |
| Rivets (Blind/Solid) | Aluminum 2117, steel, titanium | Fuselage skins, shear-critical panels |
| Threaded Inserts & Captives | Heli-Coil®, PEM, zinc-plated inserts | Composite assemblies, service access panels |
| Coatings & Surface Finishes | Zinc‑nickel, cadmium‑free, anodizing, PVD | Corrosion protection, EMI shielding |
Best Practices for Fastening Systems
- Match Solution to Load & Mission
Use high-tensile hardware in structural joints; use rivets in shear-loading applications for weight efficiency. - Select Correct Coating
Ensure finishes meet environmental demands without compromising thread fit or tolerances. - Maintain Torque & Locking Standards
Always apply calibrated tools and choose locking solutions to prevent vibration-related failure. - Ensure Traceability
Utilize DFARS- and MIL-SPEC-certified hardware with full material certifications—even for coated or specialized systems.
