Anyone have the specs for Izzy grip screws or have extras to sell?

Was working on my grips last night. Took them off the AP, left the grips and the screws on my work bench. The next morning, 2 screws were gone in a kinda cluttered garage. Looked hard but the culprits must of had a field day with them.

Those darn pesky cats! And to think I stuffed my target box with rags (thanks Rover) to protect their poor widdle ears.

They are M4 thread, 15mm long. They are "cheese head" screws, which will be hard to find. The IZH screw heads are just under 6mm in diameter. Pan heads would probably work if you grind down the head. Socket head cap screws are another option. M4 pan heads are 8mm in diamter, and socket head cap screws are 7mm, so there is less metal to remove.

Chuck the screws in an electric drill, and run the head against either a grinding wheel, or a file.

Hard to beat McMaster Carr.

I'm sure many another industrial supplier will have them as well.

The IZH uses this thread size in several places. The grips screws are 15 mm long, and the “pump lever handle” (#47) screw (#48) is 10 mm long. The palm rest screws (#79) are longer, at 20 mm. Because the team I help coach has about 20 IZH's, I bought a box of 20 mm long screws & cut them down if I need a shorter one.

# 91460A168 Metric Cheese Head Slotted Machine Screw, Zinc-plated Steel, M4 Size, 20mm Length, .7mm Pitch

The head of the McMaster Carr cheese head screws are still slightly oversized for the IZH, but they are close enough that it doesn't take much filing to get them to fit OK. They aren't available in black, but Brownell's Oxpho Blue does a nice job of blacking the heads & ends of the plain steel ones.
