What material and thickness are the beadlock rings made from?

Both the inner and outer beadlock rings are specified as 1/4" steel.

How many holes are in each beadlock ring and what size are they?

Each ring has 30 holes of Ø0.438" on a 13.688" bolt circle.

What is the outer diameter of the beadlock rings?

Both the inner and outer beadlock rings have an outside diameter of Ø16.313".

How many rings are needed?

The drawing calls for (4) required of the inner beadlock and (4) required of the outer beadlock — enough for four wheels.

How does the outer beadlock differ from the inner beadlock?

The outer beadlock has a scalloped inner profile with a Ø10.438" inner diameter and R0.250" typical corner radii, while the inner beadlock is a plain ring with a Ø11.938" inner diameter.

This is a CAD blueprint titled "BEADLOCKS" showing two circular ring components used to build beadlock wheels: an INNER BEADLOCK and an OUTER BEADLOCK, each requiring (4) pieces made from 1/4" steel. Both rings share the same key diameters: an outer diameter of 16.313", a bolt-circle-related diameter of 13.688", an inner reference diameter of 11.938", and thirty 0.438" diameter holes on a 13.688" bolt circle. The outer beadlock differs by having a scalloped (gear-tooth style) inner profile with a 10.438" inner diameter and 0.250" typical radii on the scallop corners, presumably to reduce weight while retaining clamping area. The drawing includes an empty Bill of Material table (item, qty, part number, description columns) and a standard title block noting the 1/4" steel material and a date of approximately 11/3 (year partially legible). A reader can use this drawing to fabricate a set of DIY weld-on/bolt-on beadlock rings for four wheels, with complete hole count, hole size, bolt circle, and ring diameter specifications provided.
