Product Description

Increase Product Reliability with Knurled Threaded Inserts

Knurled threaded inserts are used in conjunction with fasteners. Inserts can be threaded to ensure a perfect fit with mating parts.  Many insert applications are manufactured with threads for assembly of components.  However, threading is not always a durable system as the threads molded into the application might wear or break if they are accessed regularly.

Knurled threaded inserts are durable and can assist in removal of the screw multiple times. Using the right product not only reduces chances of damage but also increases product reliability. This reduces time and money spent in repairs, maintenance, and unplanned downtime.

Materials Used at Norwood Screw Machine

At Norwood, we provide a wide selection of traceable metals and plastics. High-grade materials are used to ensure durability and reliability. Knurled inserts are manufactured using the following materials:

  1. Brass
  2. Stainless Steel
  3. Carbon Steel
  4. Alloy Steel
  5. Aluminum
  6. Aircraft Aluminum
  7. Plastics including:
    1. Nylatron
    2. PTFE
    3. Delrin
    4. Nylon

One of the most commonly used products in this category is the brass knurled insert. Brass is a corrosion resistant material and knurled brass threaded inserts are durable and reliable. They are the preferred product across several industries looking for a resilient product that can also be plated.

Plastic products are used because they are extremely light yet tough. From aerospace to medical and manufacturing, metal, and plastic knurled inserts help improve application efficiency. Diverse materials can be used suitable for any application.  Norwood Screw Machine has been serving the industry for over 55 years. We provide standard and custom knurled threaded inserts designed, manufactured, and tested for unparalleled performance.
