Always have a camera screw driver on you! Concept inspired by Reed Harkness of
Grow Films.
Flathead designed to work with most camera screws. Tip comes out to 11.1mm x 1.8mm. Easily sanded for skinnier slots.
Designed to work with one or more neodymium magnets. Got mine at
Harbor Freight, though the actual dimensions on mine are closer to 5/16 x 3/32.
One magnet holds the bit in place, especially if your belt buckle slot isn't very wide. Two magnets is even more secure.
Not responsible for bits that may fall into urinals or elsewhere.
Tolerances should be right for using the bit in standard 1/4" drivers, and you can use the buckle to drive other bits as well!
Pictured with a 1 1/4" belt; designed to work with up to 1 1/2" width. Belt holes may need to be widened for 1/4" shank.
