## Abstract

Helical screw pile assemblies for piling and screwing into a foundation or the ground are provided. These pile assemblies comprise a disc member that mechanically engages with an elongated member causing the disc member to fasten onto the elongated member.

## Claims

### Claim 1

A method for assembling a pile comprising a disc member comprising an outer peripheral extent and an inner peripheral extent and a slot extending between the outer peripheral extent and the inner peripheral extent to form spaced-apart first and second ends, the method comprising the steps of:
axially separating the first end and the second end of the disc member allowing the disc member to form a helical shape having a central cavity defined by the inner peripheral extent;
providing an elongated member and positioning the elongated member longitudinally within the central cavity;
engaging the inner peripheral extent of the disc member with the elongated member;
fastening the disc member onto the elongated member; and
inserting each of a plurality of protruding elements displaced radially along the inner peripheral extent into one of a plurality of holes displaced helically along an outer surface of the elongated member.

### Claim 2 (depends on 1)

The method of claim 1 wherein the step of fastening comprises allowing the disc member to bias axially inwardly when each of the plurality of protruding elements displaced radially along the inner peripheral extent are inserted into one of the plurality of holes displaced helically along the surface of the elongated member.

### Claim 3 (depends on 1)

The method of claim 1 wherein the step of fastening comprises allowing the disc member to bias radially inwardly when each of the plurality of protruding elements displaced radially along the inner peripheral extent are inserted into one of the plurality of holes displaced helically along the surface of the elongated member.

### Claim 4 (depends on 1)

The method of claim 1 wherein a distance the first end and second end of the disc member are axially separated from each other is greater than an outer diameter of the elongated member.
