Jack Nut
Jack nuts have a body that splays outward against the back face of the panel when the bolt is tightened, spreading the load over a large area.
WHEN TO CHOOSE IT
Choose a jack nut for thin sheet, plastic, fibreglass and hollow panels - caravans, boats, signage, trim - where pull-through is the risk and back access is limited.
SIZES AND MATERIALS
6 stocked variants, zinc plated, M4 to M6.
Setting: these are set by tightening the bolt - no nutsert tool is needed. See the installation guide for the step-by-step method.
