Binding Barrels

Screws made from various grades of steel provide hardness, structural rigidity and durability

Lighter than stainless-steel screws and imparts non-magnetic properties

Lightweight and cheaper to use than any other material

Corrosion-, heat- and fire-resistant properties with moderate structural rigidity than steel

Nonmagnetic & an excellent conductor of electricity

Mild-to-high corrosion resistance in wet environment

Attractive black finish

Light-to-medium corrosion resistance and minimises light reflection

Decorative, mirror-like finish

High strength

Features a narrow opening to fit flat-head drive tools

When clamping objects, offers high supporting strength to multiple components

The most common type of screw driving mechanism. Has a cross shape at the centre to prevent the screw from going out of place when driven

Has a six-pointed star shape to prevent cam-out accidents. Widely used in electronic equipment

Furnishes a flat, smooth surface after installation

Creates a larger bearing surface

Also called a mushroom head; provides a larger bearing surface and a lower profile than pan or round heads

Used in applications where a flat bottom screw is required.

Most often used in socket driven screws. Becoming more common with Torx / six-lobe drives as well

Have an unthreaded head portion for high holding power. The unthreaded section of a screw is stronger than the threaded section.

Fully threaded screws are engaged with a tapped, threaded hole all the way to the head. Choose these if sideways force isn't a concern.

Wide-spaced design allowing an easy start; requires the fewest turns to tighten. Deep and thick structure that minimises the chance of stripping or jamming, even if nicked, dirty, or rusty

Closely spaced to prevent loosening during vibrations. Ideal for making precise adjustments as fine threads travel a short distance with each turn
