Fin Neck Bolts are Round Head Bolts with special Nibs under the head to assist to lock the bolt into rubber, metal or wood. Many times these parts are encapsulated with special NSF approved ABS resin or Polypropylene. The NSF approval is important because many times these parts are direct contact with our water supplies.

The encapsulation is normally black but can come in other colors. These parts are normally manufactured in 1/2" diameter in many length. Materials are normally Gr. 5, 8 or stainless Steel with coatings such Hot Dip Galvanized, Zinc plated and Geomet coating.

Tengco can supply virtually any special formed or assembled part required for the storage tank industry.All our storage tank hardware is manufactured to NSF, ANSI, SAE standards and our Fin Neck encapsulated bolts are designed to easily lock into steel or wood surfaces to assist one man bolt tightening.
