Nut & bolt 3D primivite/Mesh assembly by Dark
Please note that I didn't model these, they were attained (freely) from turbosquid, I just altered the models slightly and texture baked a variety of textures for them. They are HIGH POLY AND MUST BE RENDERED STATIC!
The nut&bolt is 1 model that has 9 interchangeable texture baked texture maps.
Also includes a washer model with 2 maps.
You can alter the maps as you please but since they are texture baked it's recommended you use effects that will effect the entire image and avoid editing individual sections too much to avoid making bad seams. So using effects like hue/saturation, brightness/contrast, levels etc should work fine.
Read 'readme' in the archive.

Import primitive, import texture maps, apply maps, size, position - enable render static for these.
