Garage Door Track Bolts & Flange Nuts, 1/4" x 5/8", Grade 8.8 Heat Treated Steel, Zinc Plated Flat Head Carriage Bolt for Vertical/Curved Rails & Extension Ladders (25 PCS)
11 sold in last 24 hours
- 【Designed for Smooth Operation】 Specifically engineered 1/4" x 5/8" length ensures a perfect fit for standard garage door vertical and curve tracks. The ultra-low profile flat head sits flush against the track interior, eliminating obstructions that could snag rollers or scratch wheels, ensuring your garage door operates quietly and smoothly.
- 【Grade 8.8 Heat Treated Strength】 Unlike standard Grade 2 or 5 hardware, our bolts are crafted from Heat Treated Carbon Steel to Grade 8.8 standards. This industrial-grade hardening process provides superior tensile strength and shear resistance, making them tough enough to withstand the heavy vibration and dynamic loads of automatic door openers without bending or snapping.
- 【Knurled Shoulder Locks in Place】 Solves the frustration of spinning bolts! The precision-formed knurled neck (ribbed shoulder) bites firmly into the square or round holes of metal tracks. This self-locking feature prevents rotation during assembly, allowing for easy, one-handed tightening with a standard socket or wrench.
- 【Long-Lasting Zinc Plating】 Constructed from durable Zinc Plated Carbon Steel, these bolts and nuts offer excellent corrosion resistance against humidity and cold environments. Ideal for unheated garages, warehouses, or outdoor ladder maintenance, preventing rust stains and ensuring the hardware remains serviceable for years.
- 【Universal Hardware Kit】 Package includes 25-pack of 1/4" Carriage Bolts and Serrated Flange Nuts. The serrated nut face adds extra grip to prevent loosening over time due to vibration. Compatible with most major garage door brands, shelf brackets, and extension ladder rung locks.
