The Screw & Bolt Shear is a bolt cutting device manufactured from very high quality tool steel which is hardened, tempered & machined to very close precision tolerances. The action of this tool is similar in nature to a "guillotine" design and is quite effective in cutting screws/bolts to specific lengths. The cutting body of the SBS-1 will accommodate screws or bolts in sizes of 4-40, 6-32, 8-32, 10-32, 10-24, 1/4-20 & 1/4-28.
What is the shortest length screw this tool can cut?
1/4" in length will be the shortest this tool will cut.
How is the necessary force applied to the tool in order to cut the screw or bolt?
You can just use the force of the palm of your hand to shear off the smaller bolts or screws and for the larger bolts and screws you can use the force of a rubber mallet.
