Tooling Balls

The shoulder on these tooling balls provides a consistent height reference point. Use the ball as a point from which any other point can be precisely measured, such as when determining hole centerlines and distances between hole centerlines.

Slip Fit, Threaded-Hole Mount

Slip-fit tooling balls have a slightly undersized shank for temporary mounting. Secure from the side with a set screw (not included).

Tooling balls with a threaded hole secure from the bottom by threading a cap screw (not included) into the shank.

Two Piece—Two-piece tooling balls are welded to the shank. If excessive horizontal pressure is applied to the ball it will break off to prevent bending the shank or distorting the tight tolerances of the ball.

Tooling Ball Covers

Unthreaded-Hole

Mount

Snap In

Snap In—Install and remove without tools. These covers have serrated prongs that slide into holes and grip the threads. They're faster to install than covers with unthreaded holes but aren't as economical.

HDPE and Nylon—In areas exposed to moisture and chemicals, these hold up better than zinc alloy covers.

Install these ball transfers in a threaded hole or use a nut to secure.

Weight capacity is given for the ball up orientation. Using these ball transfers in a ball down or angled orientation could reduce the weight capacity stated.

Steel Ball—Steel balls are durable.

Stainless Steel Ball—Stainless steel balls offer the most corrosion resistance.

Nylon Ball—Nylon balls are nonmarking and stronger than polypropylene.

Polypropylene Ball—Polypropylene balls are nonmarking and resist chemicals better than nylon.

Angled—Ball transfers with an angled working orientation can be used to form support stands.

Hitch Kits


Kit with Cotter Pin	Kit with Locking Pin

Everything you need to attach a hitch to your vehicle's receiver—these kits include a hitch insert, ball, and pin. To match the height of your trailer, you can flip them over to raise or drop the ball. The ball in these kits connects with hitch-ball couplers on trailers.

Locking—Kits with a locking hitch pin prevent your hitch from getting stolen—you can't pull the hitch insert out without the key. A dust cap keeps debris out of the locking mechanism.

For Maximum Trailer Weight—Maximum trailer weight is the total weight being towed.

Vertical Capacity—Vertical capacity (also known as tongue weight) is the weight of the load on the hitch ball.
