The set is designed to save time hunting for the right thread and length, keeping matching parts organized and ready.

Which vehicles and repairs does this kit cover?

The assortment includes 18 different thread and length combinations found across many passenger cars, light trucks, and motorcycles, including both SAE and metric standards. It replaces numerous OE part numbers commonly listed for caliper and wheel cylinder bleeder screws.

• 18 thread/length types, including M7, M8, M10 and common 1/4", 5/16", 3/8", 7/16" sizes
• Replaces many OE references such as H9411-5, H9406-5, 107391 and others
• Includes 15 dust caps to protect new screws from debris and corrosion

How does the kit make a brake bleed or replacement easier?

By supplying multiple thread pitches and lengths, the kit helps you match the correct bleeder screw on the first try, reducing downtime and preventing stripped fittings. The clear plastic case keeps parts separated and visible so you can pull the right size quickly during service.

• Five pieces of each of the 18 sizes for repeat jobs or multiple vehicles
• Transparent, compartmentalized storage for instant size recognition
• Dust caps included to seal the fitting after installation

What are the important specifications to check before installing?

Confirm thread pitch, overall length, and sealing shoulder position against the original bleeder screw to ensure a proper fit and leak‑free seal. Using the wrong pitch risks cross‑threading; always compare visually and, if needed, test-fit on an unattached caliper or spare fitting.

• Pack includes specific lengths and pitches such as M8x1.0, M10x1.25 and 3/8"-24
• Measure thread pitch and length against the old screw before installation
• Use dust caps after bleeding to keep contaminants out of the brake line

What tools and best practices should I use with these bleeder screws?

Use a proper flare‑nut or bleeder wrench sized to the screw head to avoid rounding; if possible, apply penetrating oil and allow it to soak before removal. Torque carefully and follow vehicle manufacturer guidelines for tightening to avoid damaging caliper threads.

• Use the correct wrench or socket to protect screw head geometry
• Apply anti‑seize lightly if recommended for your vehicle to ease future removal
• Bleed brakes with a proper vacuum or pressure tool and inspect for leaks afterward
