Not that I'm aware of . . . and the threaded length of the barrel is prohibitively short for adding insulation. Go to lumber yard and get a coupon of Formica. The kitchen remodeling department has racks of 2 x 3 inch samples. Drill clearance hole in your mounting surface with .03 to .05 clearance all around the jack's mounting hardware. Place a Formica insulating sheet on the back side of the mounting surface to support the jacks in isolated splendor. You can bond the insulator to the back side of the panel with E6000 so that there are no new fasteners coming through to the front. Had a few minutes this morning to drink some coffee an peruse the 'net. The rest of the family isn't up yet . . .
