The pack contains 90 screws across 18 distinct thread/length combinations and includes 15 dust caps to protect threads and prevent contamination when the vehicle is idle. This description explains what’s inside, how to pick the right screw, and real-world uses so you can decide if it suits your needs.

Which bleeder screw sizes are included and how many of each?

The kit offers 18 unique thread/length combinations across metric and SAE standards, with five pieces per size for reliable replacement options. Five extra dust caps are included to cover exposed nipples when not in service.

• Metric sizes: M7x1.0 (31.5mm), multiple M8 and M10 variants from about 25–36mm length.
• SAE sizes: 1/4"-28, 5/16"-24, 3/8"-24 (two lengths), 7/16" (20 and 24 threads, two lengths).
• Total count: 18 sizes × 5 pieces = 90 screws, plus 15 dust caps included in the set.

How do I identify the right screw for my brake caliper or wheel cylinder?

Match thread pitch and overall length to the original bleeder screw specification for your vehicle. If the original part number is known you can compare it to the manufacturer cross-references listed for many sizes in the kit.

• Measure thread diameter and pitch with a gauge or compare to the OEM part you removed.
• Check overall length to ensure the screw reaches the bleed port without bottoming out.
• Use the kit’s most common M8 and M10 sizes for many modern passenger cars; SAE sizes cover older or specialty models.

What practical jobs does this kit make easier in the shop or at home?

This assortment eliminates downtime when a stuck, rounded, or lost bleeder screw would otherwise stop a brake job. It’s ideal for emergency roadside repairs, routine brake bleeding, rebuilding calipers, or stocking a service bench.

• Replace stripped or corroded bleeder screws without waiting for a special-order part.
• Complete multiple vehicles of different makes with one kit—saves time and reduces trips to suppliers.
• Use included dust caps to protect replacement screws from dirt and corrosion after installation.

Who this kit is for: The Dsnaduo 90PCS Brake Bleeder Screw Assortment is aimed at DIY mechanics, mobile technicians, fleet maintenance personnel, and small repair shops that need a broad selection of both metric and SAE bleeder screws on hand. If you frequently service brakes on a variety of older and newer vehicles, or you want a one-time purchase to avoid service delays, this kit is a practical, space-saving solution.
