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.

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.
Square nuts have four sides, of course, which, when compared to hex nuts, provide both benefits and draw-backs for their use. Due to the fact that each side is much longer than the sides of a comparable hex nut, "rounding" of the corners is almost impossible. But tightening the nut with a wrench requires access to a full 90° turning angle, as opposed to only 60° with hex nuts.
Providing a recess for the nut to fit into, to limit its spin, is much simpler than with hex nuts. And again the longer sides mean you can allow greater tolerance without risking rounding out the corners of the hole. This also makes them ideal for use inside a track, rail, or strut system that has two parallel sides that confine movement.

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”.

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. -

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.

Pro-Tect System for Pool Enclosures
PRO-TECT Fastener Protection System consists of a nylon sleeve and a cap that, together, cover and protect the anchor screw. The PRO-TECT nylon sleeve gives protection from electrolysis, providing worry-free installation while extending the life of the product. This is very important for the harsh conditions of the coastal environments and extreme temperatures.
The PRO-TECT cap snaps onto the top of the nylon sleeve, covering the head of the Blue-Tap anchor screw. Due to its special design, the cap will not come off easily. Caps are available in White and Bronze.
By repelling water and preventing penetration, PRO-TECT reduces or eliminates the need for warranty work, increasing life expectancy of the structures. -

Mro Thread-Locker, 50ml Bottle
MRO Solutions thread-locking products are anaerobic compounds formulated for sealing, joining, fastening, retaining, and generally locking together metal components. Unlike other thread-lockers, MRO compounds are non-surface sensitive, so they do not require use of primers for curing.
Once parts are mated with MRO thread-lockers, they form a unitized assembly that resists vibration. In addition, the mated parts are sealed against attack from corrosion, internal rust, seizure, solvents, gases, and other chemicals.
