    Precise-Control Screwdriver Sets

    Image of Product. Front orientation. Screwdrivers. Precise-Control Screwdriver Sets, Plain Grip.

    Plain Grip

    Make fine-tuned adjustments on a variety of small, delicate components, such as electronics, miniature models, and microscopes. These screwdriver sets give you better control than a standard screwdriver to avoid stripping tiny screws or cracking fragile materials. Press the end of the handle with your palm to apply constant pressure while turning the body of the screwdriver with your fingertips. They are also known as precision and miniature screwdrivers.
    Chrome-Plated Steel—The bright, shiny plating resists salt water and chemicals better than other finishes and is less likely to wear off.
    Plain Grip—Made of hard plastic for durability.

    Hex Shank

    Quick-Change Hex Shank

    Have a range of bits ready to turn the most common screw styles and sizes.
    Hex Shank—Also known as insert bits, these snap into hand tools. If you want to use them with power tools, attach a bit adapter (not included).
    Quick-Change Hex Shank—Lock these bits directly into power tools. They won't wobble as much as bits paired with an adapter, so they are the best choice for high-precision tasks.
    Steel—Best for dry environments, since moisture will cause these bits to rust.

    Static-Control Precise-Control Screwdriver Sets

    Image of Product. Front orientation. Screwdrivers. Static-Control Precise-Control Screwdriver Sets.
    Protect delicate microelectronics from harmful static shocks. Also known as ESD-safe screwdrivers, these meet IEC requirements to drain static away from your workpiece before it causes damage. Precise-control screwdrivers allow for nimble, fine-tuned adjustments. Press the end of the handle with your palm to apply constant pressure while turning the body of the screwdriver with your fingertips.
    Warning: These screwdrivers conduct electricity. Do not use them near active power sources.
    Chrome-Plated Steel—The bright, shiny plating resists salt water and chemicals better than other finishes and is less likely to wear off.
    Plain Grip—Made of hard plastic for durability.

    Torque Screwdriver and Bit Sets

    Image of Attribute. Front orientation. Torque Screwdriver and Bit Sets .

    These sets include an adjustable torque driver, bits for different drive styles, and a socket adapter. To adjust torque, remove the black vinyl end cap and turn the attached adjustment key. When set torque is reached, the driver slips to disengage and stop turning the fastener, preventing overtightening. Sets come with a calibration certificate that states the product has passed a test for accuracy.
    Note: Accuracy ratings do not apply to the lower 20% of the torque range.
