Granite Surface Plate Threaded Inserts

The standard aisi303 stainless steel threaded inserts according to the table are applied with epoxy resin on surfaces for component fixing on the granite structure and tested for traction resistance.

Granite surface plate threaded inserts.

In a recent test using 3 8 16 threaded inserts an independent testing laboratory measured the force required to pull an epoxy bonded insert from a surface plate. The recommended method for using inserts in a metrology grade granite surface table. Diy method to put threaded inserts in granite. Ten plates were tested.

Threaded inserts are used to repair stripped threads in plugs and other parts or to create a new threads in a hole for fastening applications. Out of these ten in nine cases the granite fractured first. All our surface plates meet or exceed asme standard b89 3 7 2013 and federal specification ggg p 463c. Ten plates were tested.

They can also be used to convert a standard threaded hole to accept metric fasteners and vice versa. Threaded metal inserts may be installed in the surface. Eley metrology has been providing granite surface plates and tables to industry for over 40 years. For mounting points we offer threaded inserts on position dovetails in the granite or inserted steel bars with t slots.

Out of these ten in nine cases the granite fractured first. In a recent test using 3 8 16 threaded inserts an independent testing laboratory measured the force required to pull a epoxy bonded insert from a surface plate. After reaching the desired depth the cores were removed by tapping and the inserts. Our standard and custom metrology components include master squares master angles parallels and straight edges.

Starrett granite surface plate calibration calibration of granite surface plates granite parallels 2 and 4 sided granite straight edges granite tri squares granite. In metrology it is very common for customers to require threaded inserts to hold or clamp items in place during the measurement process. The average load at the point of failure was 10 020 lbs for gray granite and 12 310 lbs for black. Inserts for stone and composites inserts for stone and composites our self anchoring is a press in threaded insert that utilises a mechanical anchoring feature to provide permanent threads in panels made of marble granite or other stones as well as composites carbon corian hpl glass and other solid surface materials.
