    New Revolutionary Design, Multiplies The Force Exerted On The Handles For Strengthened Grip & Easy Cut On The Cutter Head. ..
    Instructions on use The Vernier caliper is an extremely precise measuring instrument; the reading error is 1/20 mm = 0.05 mm. Close the jaws lightly on the object to be measured. If you are measuring something with a round cross section, make sure that the axis of the object is perpendicular to the caliper. This is necessary to ensure that you are measuring the full diameter and not merely a chord. Ignore the top scale, which is calibrated in inches. Use the bottom scale, which is in metric units. Notice that there is a fixed scale and a sliding scale. The boldface numbers on the fixed scale are centimeters. The tick marks on the fixed scale between the boldface numbers are millimeters. There are ten tick marks on the sliding scale..

  • Long Arm Ball Point Hex Ket Set - 7pc (Metric 1.5 ~ 6mm)
    A hex key or Allen key is a tool of hexagonal cross-section used to drive bolts and screws that have a hexagonal socket in the head (internal-wrenching hexagon drive). Some features of hex keys are: The tool is simple, small and light The Ball End contact works in hard to reach areas eith an 25 degree Angle entry There are six contact surfaces between bolt and driver The tool can be used with a headless screw The screw can be inserted into its hole using the key Torque is constrained by the length and thickness of the key Very small bolt heads can be accommodated The tool can be manufactured very cheaply, so one is often included with products requiring end-user assembly Either end of the tool can be used to take advantage of r..
