The Boltster Flexible Bolt and Fastener Organizer solves the problem of misplaced bolts and fasteners. Made with high strength silicone, the Boltster is chemical resistant and heat resistant up to 500 degrees Fahrenheit. The main holes fit bolts as small as M7 and as large as M17. Smaller fasteners can be flipped, allowing for secure organization. The perimeter holes are the smallest, allowing all small screws, rivets, dowels, and body panel clips to be securely stored. A large pad allows for labeling projects (water pump, alternator, etc.) Other uses include storing drill bits, dowels, studs, rivets or other small tools and fasteners.
