ESD Strap Bench Ground Anchor
A bench anchor for an ESD wrist strap. You screw it to the bench with two #8 wood screws (4.5 mm clearance holes). A captive M4 hex-head bolt (7 mm hex pocket) points up as a ground stud for a ring terminal and a wing nut. The strap's coiled cord wraps around a flanged post 16 mm across and 39 mm tall, so it stops dragging across the boards you're handling. The whole part is 110 x 40 mm.
Air Hose Wall Pass-Through Trumpet
This screw-on grommet fits a 1-1/2 in (38.1 mm) hole-saw hole. It lets an air line, shop-vac hose or extension cord pass through a garage wall or into a compressor closet without the hose rubbing on raw drywall or stud edges. The part has a 76 mm flange with three countersunk #8/M4 screw holes (4.5 mm) and a 28 mm bore that flares at 45° to 40 mm on the room side. A 25 mm crush-ribbed sleeve press-fits the hole.
