Shear Stock

Definition - What does Shear Stock mean?

Shear Stock is a material stock used to produce shear pins. This stock is either made from brass or steel because the oil and gas industry uses brass or steel made shear pins. Shear Stock is a precision manufactured stock which comes in various sizes whose material should have precise characteristics needed to prepare the shear pins.

Petropedia explains Shear Stock

Shear Stock can be in the shape of a rod or a bar from which shear pins can be cut. The material used to manufacture the Shear Stock is generally brass or steel as the properties of these materials show positive shearing effect when adequate amount of shear force is applied. The shear pins produced from the Shear Stock can be used in downhole slickline tools to hold sliding components onto their positions until an external suitable shear force is applied and the shear pin is broken. Once the pin is sheared or broken, the sliding components are released and can move.
