The offset clips are zinc plated in silver color.
The screws are wood screws in a black oxide color. The screws are versatile - a Phillips or flathead screwdriver can be used.
You can choose which size you want and how many screws you would be needing. Some people choose to use the screws only on the liner/frame without screwing holes into the actual wood canvas stretch bars.
TO SELECT THE APPROPRIATE SIZE: (See diagram in photos)
1) Measure canvas depth (in inches)
2) Measure rabbet depth (in inches)
3) Canvas depth - Rabbet Depth = Offset Canvas Clip Size
If you have any questions/concerns, feel free to ask. Thank you!
