Plastic Head & Crank Bags - 3mil (100)

The Plastic Head & Crank Bags - 3mil (100) provide a critical protective barrier for internal engine components during long-term storage or transit. Designed specifically for professional engine builders and automotive machinists, these heavy-duty bags prevent contaminants like dust, moisture, and debris from compromising precision-machined surfaces. By utilizing these specialized covers, you ensure that expensive cylinder heads and crankshafts remain in pristine condition until they are ready for final assembly.

Each bag is constructed from 3mil thick polyethylene, offering a robust level of puncture resistance and durability that standard plastic wraps cannot match. This specific thickness is chosen to handle the sharp edges and significant weight of metal engine parts without tearing or stretching excessively under load. The Pioneer EB-20-100 pack includes 100 individual bags, providing a high-volume solution for professional workshops that need reliable protection for multiple components simultaneously.

These bags are an essential addition to any machine shop’s tool inventory, particularly when returning finished components to customers or storing parts for seasonal builds. They are sized to accommodate a wide variety of automotive engine heads and crankshafts, providing a versatile fit for most standard engine platforms. When you buy these bags, you are investing in the long-term integrity of your mechanical work by preventing the flash rust and oxidation that often occurs in humid garage environments.
