Product Details

ARP 400-8767 fine thread nyloc hex nuts are precision-engineered fasteners constructed from aerospace-quality materials to meet the demanding requirements of high-performance engine applications. Each nut features an integrated nylon locking insert that resists loosening from vibration and thermal cycling, ensuring reliable clamping force throughout the engine's service life.

Key Features:

  • Rated at 180,000 PSI tensile strength for extreme load-bearing applications
  • Aerospace-quality materials ensure consistent performance under high stress and temperature
  • Black oxide finish provides corrosion resistance and professional appearance
  • Nylon locking insert prevents self-loosening without thread damage
  • Manufactured to ARP's exacting quality control standards
  • Includes 5 hex nuts per package

These fine thread nyloc hex nuts are ideal for cylinder head applications and other critical engine fastening requirements where reliable torque retention and superior material strength are essential. The nylon insert design allows for repeated installation and removal while maintaining locking effectiveness.

part arrived on time and as described at a great price!

Site use was easy, and product shipped promptly after ordering. Price was the best I could find, would use this business again.

Fast and easy

Lowest price on EBC brakes for my Subaru. Good speed on processing.

First I found Autoplicity through The Find, they already had the item discounted, other than all the other online stores where you needed to search for coupon codes. Then the transaction was very simple, they accepted PayPal which was the payment method I wanted to use.<br>I'm very happy with my purchase and the service I got from Autoplicity.

Ordered a CAI kit and Autoplicity had the lowest price. They're website didn't correctly match my vehicle to the product and it took a few days to ship. They're support was friendly and quick when I emailed them about the delay.

Autoplicity had the lowest price on what I ordered. Autoplicity was $30 cheaper than other competitors. I will return to Autoplicity again
