## Abstract

The bucket elevator construction bolt comprises a flat head and a threaded shaft, the bolt further incorporating a collar adjacent the head, the collar including a plurality of elongate, radially arrayed spline teeth which engage within the material of the elevator belt, maintaining the bolt position against radial torque or vibratory forces applied thereto.

## Claims

### Claim 1

A bucket elevator construction bolt comprising a shaft having a substantially planar head at one end thereof, the head having a flat top surface and a bottom surface, the bolt further including a splined tooth collar on the shaft thereof, extending along the shaft a predetermined distance from the bottom surface of the head, the collar being of a diameter larger than a diameter of said shaft, with each splined tooth extending radially outwardly of said collar, and the shaft being threaded from a point proximate the collar to a free end thereof.

### Claim 2 (depends on 1)

The bolt of claim 1 wherein the collar extends a predetermined distance along a length of said shaft.

### Claim 3 (depends on 2)

The bolt of claim 2 wherein each splined tooth extends across an entire length of said collar.

### Claim 4 (depends on 3)

The bolt of claim 3 wherein each splined tooth is parallel to an adjacent splined tooth.

### Claim 5 (depends on 4)

The bolt of claim 4 wherein each splined tooth is perpendicular to threads of the threaded shaft.
