This bolt kit matches OEM measurements but is far superior when it comes to corrosion resistance, strength and durability.

Class 10.9 steel is at least 25% stronger than medium-strength steel screws. The flange distributes pressure where the screw meets the surface, eliminating the need for a separate washer.

  • Black-Phosphate Bolts
  • Black-Oxide Nuts
  • Class 10.9 Steel
  • Flanged Hex Head
  • Black corrosion-resistant-coated steel is more corrosion resistant in wet environments than zinc-plated steel 
  • Screws meet ISO 898-1 and comply with specifications and testing requirements for material quality.

Kit Includes:

(x4) 10.9 Grade Flanged Hex Head Bolts

(x4) 10.9 Grade Flanged Hex Head Nuts
