    Stainless Steel Button Head Hex-Drive Screws

    Image of Product. Front orientation. Rounded Head Screws. Stainless Steel Button Head Hex-Drive Screws.
    These button head screws won't corrode from moisture and chemicals, but they aren't as strong as alloy steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
    Length is measured from under the head.
    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.

    Steel Button Head Hex-Drive Screws

    Image of Product. Front orientation. Rounded Head Screws. Steel Button Head Hex-Drive Screws.
    Made of alloy steel, these screws have nearly twice the tensile strength of other steel screws. The button head looks similar to a pan head, but it's lower and more compact, taking up less space. With six contact points, the hex drive withstands more torque than slotted and Phillips to securely grip your driver.
    Length is measured from under the head.
    Black-Oxide Alloy Steel—Typically chosen for their appearance, these screws have a dark, matte coating to create a finished look. They offer minimal corrosion resistance, so they're best for dry environments.

    Fully Threaded

    About half the strength of medium-strength bolts, these Grade 2 bolts are for light duty fastening. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Material meets ASTM A307 or SAE J429 specifications for quality. Dimensions meet ASME B18.5 specifications. Length is measured from under the head.
    Zinc Plated—Zinc-plated steel bolts resist corrosion in wet environments.

    Made from 18-8 stainless steel, these bolts have good chemical resistance and may be mildly magnetic. They're a good choice for ACQ-treated (arsenic-free) lumber. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Length is measured from under the head. Dimensions meet ASME B18.5 or DIN 603 specifications. Some also meet ISO 8678. DIN 603 is functionally equivalent to ISO 8678 with slight differences in head diameter, head height, and length tolerances.
    Match the thread spacing of mating components.
    Coarse Thread—Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.

    Fully Threaded

    Made from Grade 5 steel, these bolts are suitable for fastening most machinery and equipment. A square neck keeps them from turning when tightening a nut. A smooth, rounded head provides a finished look. Grade 5 steel bolts are marked with three radial lines. Material meets SAE J429 specifications for quality. Dimensions meet ASME B18.5 specifications. Length is measured from under the head.
    Black Oxide—Black-oxide steel bolts are mildly corrosion resistant in dry environments.
    Zinc Plated—Zinc-plated steel bolts resist corrosion in wet environments.
    Zinc Flake Coated—Zinc-flake-coated steel bolts are 40 times as corrosion resistant as zinc-plated bolts and comparable to Magni-coated bolts.
