AVS Bug Deflector Screws – OEM Replacement Hardware
Our AVS bug deflector screws deliver the secure, weather-resistant fastening your hood shield installation demands. Engineered specifically for AVS aerodynamic bug deflectors, this stainless steel hardware set includes everything needed to mount your deflector with confidence.
Each screw is precision-machined to exact OEM specifications, ensuring a flush fit that won't compromise your vehicle's finish or the deflector's aerodynamic profile. We designed these fasteners to withstand years of highway driving, temperature cycling, and exposure to road spray without loosening or corroding.
Hardware specifications
Materials & Corrosion Resistance
We manufacture every AVS bug deflector screw from marine-grade 304 stainless steel, the same alloy specified for coastal automotive applications where salt exposure accelerates metal degradation. This austenitic steel composition contains 18% chromium and 8% nickel, forming a passive oxide layer that self-heals when scratched.
The washers feature a dual-layer finish: zinc-plated steel for load distribution, with a polymer-coated underside that creates a barrier between metal and your vehicle’s painted surface. This design prevents the galvanic corrosion that occurs when dissimilar metals contact in the presence of moisture. Laboratory salt-spray testing confirms our hardware maintains structural integrity through 500 hours of simulated severe-weather exposure, equivalent to approximately five years of highway driving in northern climates.
Thread Specifications & Torque Requirements
Standard Thread Dimensions
The M6 × 1.0 metric thread we use across all AVS bug deflector screws matches the factory-drilled mounting points in our deflector brackets. Thread engagement depth measures 12mm, providing eight full threads of contact with the steel mounting insert molded into each deflector.
Proper Installation Torque
We recommend tightening each screw to 4.5 Newton-meters (40 inch-pounds) using a calibrated torque wrench or driver. This specification creates sufficient clamping force to prevent vibration loosening while staying well below the 8 Nm yield point where thread stripping or bracket deformation could occur. Hand-tightening followed by a quarter-turn with a standard screwdriver approximates correct torque for installers without precision tools, though we include a torque spec card with every hardware set for reference.
What's Included in Each Set
Every AVS bug deflector screws package contains eight complete fastener assemblies, sufficient for one standard hood deflector installation. Each assembly includes one M6 × 1.0 screw (20mm overall length, 12mm threaded portion), one M6 stainless flat washer, and one polymer isolation washer.
We also include a printed installation guide card that lists torque specifications, provides a tightening sequence diagram for even pressure distribution, and notes the break-in inspection recommendation. Most AVS deflector models use six mounting points, so the eight-screw set provides two spares for future replacements if a fastener is lost during deflector cleaning or seasonal removal.

Common Questions About AVS Bug Deflector Screws
Our screws use the M6 × 1.0 metric thread standard common across many automotive hood shields, so they may physically fit other brands' deflectors. However, we engineer these fasteners specifically for the mounting bracket thickness and hole diameter found in AVS products. Thread engagement depth and torque specifications assume AVS bracket construction. Using them with non-AVS deflectors may result in improper clamping force or installation difficulty.
We recommend inspecting mounting hardware every six months or 10,000 miles, whichever comes first. Check for visible corrosion, thread damage, or any loosening that allows deflector movement. In salt-belt regions or coastal areas, inspect quarterly during winter months when road treatment chemical exposure peaks. Replace screws immediately if you notice rust staining, stripped threads, or if any fastener requires excessive force to tighten.
Yes, our stainless steel screws tolerate multiple installation cycles when handled properly. Inspect threads carefully before reuse—any visible deformation, galling, or corrosion means replacement is necessary. Clean threads with a wire brush to remove accumulated road grime before reinstallation. If you remove and reinstall your deflector seasonally, plan to replace hardware every three to four cycles as a preventive measure, since repeated torquing gradually work-hardens the threads.
Our AVS bug deflector screws feature a 10mm hex head. Use a 10mm socket with a ratchet or torque wrench for installation. A standard Phillips #2 screwdriver also fits the recessed cross-drive in the screw head if socket access is limited in tight engine bay areas. For best results, we recommend a torque-limiting driver preset to 4.5 Newton-meters to ensure consistent clamping force across all mounting points.
Each screw includes a polymer isolation washer designed specifically to prevent paint damage. The washer's coated underside creates a protective barrier between the metal fastener and your vehicle's finish. Install the polymer washer directly against the painted surface, then place the metal flat washer on top before threading the screw. This layered approach distributes clamping pressure while preventing metal-to-paint contact that causes scratching or galvanic corrosion.
We sell complete screw assemblies only, not individual washers, because proper fastener performance requires matched components. Each set includes eight complete assemblies with two spares beyond the six screws most deflector installations require. If you need additional washers, purchasing another complete hardware set ensures you have the correct washer diameter, thickness, and coating specification matched to our screw design.
Our hardware carries a limited lifetime warranty against defects in materials and workmanship. This covers manufacturing flaws such as thread defects, material composition errors, or coating failures under normal use conditions. The warranty does not cover damage from improper installation, over-torquing, cross-threading, or corrosion resulting from failure to perform recommended maintenance inspections. Contact our customer service team with your original purchase receipt if you experience a warranty-covered issue.
