  • 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. 

  • Wood Screws

    Wood screws are made to join two pieces of wood together and securely hold them. There are many styles of wood screws available today, from various driver tools to what material the wood screw is made from.

  • Wing Nuts

    Wing nuts are a type of specialty nut with a pair of wings to enable it to tighten without tools. The wings provide a grip for the thumb and finger for turning. They are commonly used where frequent adjustments or removals are needed, and can be made quickly at a later stage.
    An alternative form of the wing nut has a washer built in, and is used to storm-proof the windows of a building. This washer face allows the wing nut to be used to secure plywood onto fixed anchors, where the hole in the plywood will be larger than the anchor studs it and the wing nut are being mounted on. This provides the advantage of having a larger surface bearing the pressure, while also eliminating the need of a separate washer that will often fall and get lost during storm-prep installation.

  • Aluminum Key Hole Washer

    Aluminum key-hole washers are commonly used with combo truss machine screws and sidewalk bolts. They are used as an additional backing plate when storm panels keyways do not line up correctly. They are also often used to provide additional backing when sidewalk bolts have been changed out to truss head screws. They can be placed on after panels are installed.

  • T-Nuts

    T-nuts are barrel shaped fasteners with internal threading, and are used to provide an anchor point for a bolt in a piece of wood, whether a flat board or a dimensional piece. They are especially useful when a flush surface is wanted. T-nuts have a flat base with prongs bent up at 90° angles, parallel to the barrel. After pre-drilling a hole, the t-nut can be fixed in place either by tightening a bolt into it from the top, which pulls the prongs into the wood, or using hammer to pound the locking prongs into the wood until flush.

  • F-Track Bolts

    The square head of these F-Track Bolts fits perfectly into all flat and angled storm panel F-Track.

  • Sidewalk Bolt, Stainless Steel

    Also known as shutter screws, the ultra-wide truss head distributes the load over a large area for excellent holding pressure when placing plywood, metal, and fabric hurricane panels or removable track. Made of 18-8 stainless steel, these screws are chemical resistant and may be mildly magnetic.

  • Square Nuts, Zinc

    As the name implies, square nuts have a 4-sided, square design. This square profile provides a greater bearing surface when installing onto a bolt. Square nuts are designed for use with square headed bolts, and the large surface provides better resistance to loosening. When using square nuts, as with hex nuts, use flat washers of the correct size and material.
