  • Hanger Bolts

    Hanger bolts are a special type of stud that have a lag screw thread on one end and a machine screw thread on the other. They are ideal for tie-wire or overhead applications such as hanging ductwork, fixtures, or suspended electrical wiring from wood beams or walls.

    Our hanger bolts are available as either a plain finish, or zinc plating for corrosion resistance.


    Drywall screws fasten sheets of drywall (also called sheetrock or plasterboard) to the wall or ceiling support studs. Drywall screws with coarse threads are used to to attach to wood framing. Screws with fine threading are used for metal studs. Also, self-drilling versions are available for attaching to thicker metal support.
    Most drywall screws have a tapered bugle head to penetrate the drywall without damaging the outer layer of paper. Trim head screws are used to attach trim pieces over the drywall, and have a very small head that disappears into the surface for easy finishing. K-lath screws have a large wafer head to easily attach wire mesh, or lath, to the frame studs to support plaster. Their low profile heads are easily covered over by the finished surface of tile, stone, brick, stucco, etc.

  • Tek Self-Drilling Screws

    Teks screws provide secure fastening to metal with strong holding power, without the need to pre-drill. High performance cutting tips are designed to quickly penetrate the metal surface for easy installation. Self-tapping threads ensure strong holding power, in either sheet metal or steel beams. There are even Teks screws for wood-to-metal applicaitons.
    Standard grade Teks screws are ideal for attaching HVAC, electrical work, metal framing, and general light to medium applications. The TRAXX grades are designed for heavier applications, and are available in Stainless Steel and Hardened Steel.
    There are also several types that include neoprene washers, to seal the drill site against rain or other water.
    Please answer the following questions to find the exact Teks screw that you need.

  • Lag Screw, Hex Head

    Manufactured to be extremely sturdy, lag screws are some of the toughest fasteners. They are used to attach objects to wood and anchor masonry. Common applications include retaining walls, deck frames, and wooden beam outdoor play equipment. For masonry application, use the screw in conjunction with a lag shield. Lag screws have coarse threads designed for pre-drilled holes to prevent splitting or snapping, and require minimal clearance above the fastener. The hexagonal drive allows for simple installation and controlled traction with a socket or wrench.

    For corrosion resistance, lag screws are available as Zinc plated, Hot Dipped Galvanized (HDG), and Stainless Steel.

  • Hex Tap Bolts

    The major distinguishing feature of hex tap bolts is that they are always fully threaded from under the head to the tip, no matter the size. Other features, such as chamfered point or washer bearing surface under the head, may be present, or may not. Tap bolts are meant to be used nuts to secure two objects together, but they also will fully seat into a tapped hole to secure one material to a base material.
    They are available in Grade 2, Grade 5, and in Stainless Steel.

  • Hex Cap Screws, Grades 2, 5, & 8

    A hex cap screw is a six-sided bolt with a trimmed hex head and a washer face on the bearing surface. Informally, it is also called a Finished Hex Bolt. Hex cap screws have tighter tolerances than standard bolts of the same size, and so are often used where precise tolerances are needed. The standard hex screw specifications include ASTM A449 and SAE J429 Grade-2, Grade-5, and Grade-8.

  • Sheet Metal Screws

    Sheet metal screws, a type of self-tapping screw, have threads down the entire length of the shank for tapping and fastening thin material. The point style determines the type of material the screw can be used on, such as metal, wood, or plastic. These screws commonly have a sharp point that helps penetrate the material.

  • Machine Screws

    Machine screws are meant to hold two metal work pieces together, with the use of a threaded pre-tapped hole, or through a hole and held with a nut. They are threaded the entire length of the shank. For most styles of a machine screw, the length is measured from under the head to the end of the screw. For flat head machine screws, since they are intended to fit into a countersunk hole, their length is measured from the top of the screw head to the end of the screw.

  • Set Screws, Cup Point

    Set Screws are essentially a headless bolt, which has a hex socket in the driving end. They are commonly used when a protruding head would be in the way of other moving parts. Their most common function is to secure two parts together, but without a pre-determined positioning point between them. A prime example is fixing a pulley wheel along a drive shaft, where the set screw in the wheel’s hub is tightened into the side of the drive shaft and holds them tight due strictly to friction.

    Set screws are available either as a black hard steel alloy, or as stainless steel.
    Because of its headless shape, and how it bores through its hole, a set screw is also known as a “grub screw”.

  • Cylindrical Head Socket Cap Screw

    Socket cap screws have a small cylindrical head with tall vertical sides, and with recessed hex-shaped sockets with which to drive them. Because they are driven with hex keys (Allen wrench) or hex socket bits, they are ideal for applications where limited clearance would not allow the use of wrenches and sockets. In addition, the driving surface is protected from external damage and provides six sides of contact surface for added torque.

  • Flat Head Socket Cap Screws

    Socket cap screws are commonly used in machine parts, die fixturing, and clamping. The flat socket head enables driving where there is not sufficient space for wrenches or sockets, and allows the screw head to sit flush with the surface.
    Socket cap screws are available as either an alloy with a blackened oxide finish, or as stainless steel. Also, they feature either coarse (UNC) or fine (UNF) threading.

  • Button Head Socket Cap Screw

    The button head version of socket cap screws are commonly used for removable panels, machine parts, die fixturing, and clamping. The socket head enables driving where there is not sufficient space for wrenches or sockets. The button head offers a wider bearing surface and high tensile strength, but offers lower profile than standard socket cap screws.
    Button Head socket cap screws are available as an alloy with black oxide finish, or as stainless steel.
