 A. Raymond Tinnerman® & Palnut® (aka PAL) of Tinnerman Palnut Engineered Products, Inc. are leading brands in specialty clip-type fasteners including the world's largest selection of spring steel, stainless steel, and plastic engineered fasteners. Their fasteners replace traditional fastening methods with innovative solutions combining aesthetics and functionality. They are quick and easy to install, and do not require mounting tools.

Nuts and anchor nuts are extensively used fasteners in a wide range of applications in defence, aerospace, automotive, construction, and many other industries.They come in countless combinations of types, sizes, thread types, materials finishes & protective coatings and conforming standards.

Anchor nuts, aka nut plates, nut plates or anchor plates, are terms used interchangeably and relate to stamped sheet metal fasteners with an internally threaded tube and a plate with two clearance holes for rivets. Initially designed and still extensively used in aerospace applications, they are today also used in automotive, motorsports, and many other industries in blind mounted panel applications where hex nuts cannot be used or an attached nut is required for ease of maintenance.

Nylon locking nuts, also termed as stop nuts, nyloc, elastic stop, nylon-insert lock or polymer-insert lock nuts, are threaded hex nuts with a nylon insert, or collar, which is smaller than the thread diameter. As the nylon insert lock nut is tightened, the collar deforms over the mating screw/bolt threads, increasing friction on them, thus resisting vibration and loosening and maintaining reliable locking performance.These nuts are a preferred choice for equipment exposed to movement or vibration.

Below is a non-exhaustive compilation of anchor nuts conforming to the DIN LN Aerospace Standards. Standards marked with (*) are inactive for new designs.
