307 Or 308 Self Tapping Insert

Product Detail

Self Tapping Inserts (also known as self threaded inserts or Ensats) are cylindrical metal bushings with internal and external threads and are specially designed to cut their own threads as they are being driven into a drilled hole. They provide permanent wear-resistant threads in a wide range of materials, from tough to tap, high strength steels to brittle plastics.

The thread cutting action is performed by the cutting slots on the insert. By tapping its own thread, the self tapping insert eliminates the need for pre-tapped holes.

Features & Benefits:

Self tapping - no pre-tapping required

Very high pull-out resistance

Highly resistant to vibration, can withstand vibration without loosening

Produces high quality, permanent, wear-resistant threads

Unlimited thread re-usability

Protects expensive components from damage

Easy to install, standard taps can be used

Wide variety of styles to fit almost every application

Applications:

Passenger & commercial vehicles, engines, transmissions, radiators

Marine

Military applications - tanks, aircraft

Plant & equipment construction

Office machinery

Household appliances - vacuum cleaners, cameras, sun lamps

Heavy machinery

Materials: 303 SS; Brass
