Go Kart Engine Mount Bolt Kit, 4 Sets Grade 5 5/16" x 1-1/2" Flange Bolts & Nylock Nuts for Predator 212cc 224cc, GX160 GX200 Clone, Mini Bike Engines

This go kart engine mount bolt kit includes 4 Grade 5 flange bolts and 4 matching nylon-insert lock nuts for small engine mounting applications. The 5/16" x 1-1/2" bolt size is commonly used for securing compatible engines to go kart, mini bike, drift trike, and small 4-stroke engine mount plates or slotted mounting bases. The kit is designed for many small engine setups, including Predator 212cc / 224cc style engines, GX160 GX200 clone engines, 196cc clone engines, and other 3HP-7HP engine applications. The flange-head bolt design provides a broad contact surface, while the nylon-insert lock nut helps reduce loosening during normal vibration-prone operation. Before purchase, please compare your original hardware, bolt diameter, bolt length, engine base hole size, mounting plate thickness, and clearance around the engine base. This aftermarket mounting hardware kit is suitable for repair, replacement, and custom small engine installation projects.

• Complete 4-Set Kit: Includes 4 Grade 5 flange bolts and 4 matching nylon-insert lock nuts for go kart, mini bike, drift trike, and small engine mounting applications. Suitable for securing an engine to a compatible mount plate or slotted base plate.
• 5/16" x 1-1/2" Size: Each bolt measures 5/16 inch in diameter and 1-1/2 inches long, a common size for many kart engine mount setups. Please compare your original hardware, engine base holes, and mounting plate thickness before ordering.
• Compatible Applications: Designed for many small engines used on go karts and mini bikes, including Predator 212cc / 224cc style engines, GX160 GX200 clone engines, and 196cc 3HP-7HP engine setups. Please verify fitment before purchase.
• Flange Bolt Design: The flange-head structure provides a wider contact surface than a standard hex bolt, helping spread pressure across the mount area without requiring an extra washer in many compatible installations.
• Nylock Nut Structure: Matching nylon-insert lock nuts help reduce loosening during normal vibration-prone use. Ideal for engine replacement, go kart repair, mini bike service, small engine builds, and custom mounting projects.
