    Flanged Knurled-Head Thumb Nuts

    Image of Attribute. Front orientation. Contains Annotated. Thumb Nuts. Flanged Knurled-Head Thumb Nuts.
    The slip-resistant head is easy to grip, while the flange distributes pressure evenly across the mounting surface without the need for a separate washer. These nuts are often used to secure screws in oversized or irregularly shaped holes since the flange covers a larger area than standard nuts.
    Brass
    Brass—With a warm, polished look, these nuts are often chosen for their appearance. Similar to 18-8 stainless steel, brass is corrosion resistant enough to stand up to wet environments. It is also softer than other metals, so it's easier to thread together.
    Zinc-Plated Brass—The zinc plating offers better corrosion resistance than plain brass to stand up to solvents and mild chemicals.

    Wing Nuts

    Style 1

    The easiest nuts to twist on and off by hand, these are commonly used to fasten parts that need to be frequently disassembled, such as access panels and covers. The wings give you more leverage than knurled-head nuts, so you can apply greater torque and achieve a tighter fit.

    Square Nuts—Right-Hand Thread
    Image of Product. Front orientation. Lead Screws and Nuts. Acme Lead Screws and Nuts, Square Nuts—Right-Hand Thread.
    Square nuts fasten and position lead screw components. Square nuts have large sides, which make them easier to grip with a wrench than hex nuts and keep them from rotating in channels and square holes.
    360 Brass—360 brass components have excellent machinability and good corrosion resistance.
    Travel Distance per Turn—Travel distance per turn, also known as screw lead, is the distance a nut or handle moves with one revolution of the lead screw.
