    Tight-Clearance Ratchet Wrenches

    Two Heads

    Rather than teeth, these wrenches use a series of rollers to engage the ratchet, enabling work in the tightest of spaces. Also known as silent ratchets, they don't make the traditional clicking sound when turned. The smaller the turn required to ratchet, the less clearance you need to engage the ratchet.
    1 Head—Wrenches with one head can ratchet in both directions, but you’ll need to remove the square drive with pliers and insert it on the opposite side of the head. The square drive is held in place with a retaining ring.
    2 Heads—Wrenches with two heads ratchet in both directions—simply flip them around to switch between clockwise and counterclockwise rotation.

    Tight-Clearance Self-Aligning Steel Swivel-Tip Set Screws

    Image of Product. Front orientation. Contains Annotated. Set Screws. Tight-Clearance Self-Aligning Steel Swivel-Tip Set Screws.
    With a low-profile tip, these screws fit in compact assemblies, shallow mounting holes, and precision equipment where space is limited. The tip pivots to conform to your workpiece's surface without damaging it. Made of alloy steel, they're strong enough to hold components without wearing down.
    Black-Oxide Alloy Steel—These screws have a dark matte finish that offers minimal corrosion resistance, so they're best for dry environments.

    Tight-Clearance Self-Aligning Stainless Steel Swivel-Tip Set Screws

    Image of Product. Front orientation. Contains Annotated. Set Screws. Tight-Clearance Self-Aligning Stainless Steel Swivel-Tip Set Screws.
    Our most corrosion-resistant swivel-tip set screws. Made of stainless steel, they won't rust, but they're not as strong as alloy steel. With a low-profile tip, these screws fit in compact assemblies, shallow mounting holes, and precision equipment where space is limited. The tip pivots to conform to your workpiece's surface without damaging it.
    18-8 Stainless Steel—The choice for wet and outdoor environments, these screws won't rust. However, they don't hold up to the harsh chemicals that 316 stainless steel can.
