Product Description

Press fit nuts are round and internally threaded. Their outer diameter is knurled. The knurled clinching ring that surrounds the shank provides a better grip to the fastener. These one piece fasteners are designed to press fit into holes. An arbor press machine is used to press these fasteners into a plain hole. These nuts are fixed on both the sides of a panel. The inserts or nuts are widely used in the flooring of an aircraft for fastening panels to the structure of the aircraft. Therefore, these fasteners are also known as floor panel inserts. One of the biggest advantage of press fit nuts is that each nut has a capability to carry large weights up to 2000 lbs. Norwood Screw Machine Parts is a leading and one of the most experienced manufacturers of press fit nuts. We can provide you with the high-quality custom nuts based on your design requirements.
