IN13 Knurled Body Knock-In Insert Nuts with Collar are designed to be used in applications where the decorative flat head remains visible. They have a knurled shank which should be driven into the wood with a hammer using a pilot hole of the appropriate size. Each insert has a collar which prevents over-insertion. A board can then be attached from above utilising a flathead screw which screws into the standardised internal threads.
Available in sizes from M3 to M10, these knock-in inserts are precision made from steel, brass and stainless steel. They are available in a variety of lengths from 8mm to 12mm. Diameters from 5.5mm to 12.5mm are available with head diameters from 8mm to 18.5mm.
Available in a range of sizes – see stock chart below for full specifications. Non standard sizes available to order.
