Pearl Bass Drum Tension Bolt Set of 10 - Junk ・Based on the 1995 parts list, these are likely T-075. These are Pearl bass drum tension bolts with a 6mm thread size. (Please note: these are not 7/32 size) ・There are scratches, rust, etc. ・Washers are not included. I have confirmed that they function as tension bolts by threading them into a 6mm female thread (Images 7 & 8). The memory lock in images 7 & 8 is a part for photography purposes and is not included in the product. Please consider these as junk parts that have been stored in a warehouse for a long time.
