Product Identity
The Midwest Fastener 66565 pack supplies ten brass fine-thread bleeder caps for hydraulic brake or clutch systems. Each cap fits a 3/8"-24 thread and measures 7/16" across the hex. The components are new and intended for automotive maintenance or repair work.
Critical Fit
The decisive specification is the 3/8"-24 fine-thread pitch combined with the 7/16" hex size; only systems using that exact thread will accept these caps. Verify the thread specification on the vehicle or component before ordering.
Buyer Guidance
Mechanics and DIYers servicing brake or clutch hydraulics with matching 3/8"-24 bleed ports will find the ten-piece quantity convenient for multiple jobs. Shops needing a different thread pitch, a larger hex, or a non-brass material should look for alternative fittings.

Questions about this item
What does the 3/8"-24 thread size mean when I install these caps on my brake bleeder valves?
The 3/8"-24 fine thread matches standard bleeder screws on many domestic and import vehicles, so the caps screw on by hand to keep dirt and moisture out of the hydraulic system.
How does the brass construction hold up against brake fluid and road salt?
Brass resists corrosion from glycol-based brake fluids and winter road treatments, so the caps stay removable for future service without seizing or rounding off.
Will the 7/16" hex head fit my existing bleeder wrench or socket?
Yes, the 7/16" hex is a common size that works with standard flare-nut wrenches and 6-point sockets used for brake bleeding jobs.
