Metric Hex Bolts & Cap Screws, Class 8.8 Yellow Zinc

Metric hex bolts (partially threaded) and cap screws (fully threaded) are threaded fasteners with a hexagonal head, designed to be used with a nut for tightening. Hex bolts and cap screws come in different grades, indicating their strength and material composition. They are commonly used in construction, machinery, and automotive applications. The length of a hex bolt or cap screw is typically measured from under the head to the end of the bolt or cap screw.

Both hex bolts and cap screws come in various materials such as steel, stainless steel, and brass, and they are available in different thread pitches and diameters to suit specific requirements. When choosing between them, consider factors like accessibility for tightening, clearance, and aesthetic preferences.
