The standard for high-strength fastening.
These metric alloy steel screws are nearly twice as strong as stainless steel button head screws.
Choose these metric screws for high-strength fastening. Often used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems, these screws are at least 25% stronger than medium-strength steel screws.
About 25% stronger than medium-strength steel nuts, these nuts are comparable in strength to class 10.9 bolts.
Half as thick as regular hex nuts, these nuts fit into spaces with low height clearances. They are about half as strong as medium-strength steel, and are often used for light duty applications, such as securing access panels.
Use these metric washers to evenly distribute the load under bolt or screw heads and nuts when fastening. They can also act as spacers.
Compared to our general purpose washers, these have exaggerated diameters and/or thicknesses. Use them to cover oversized holes, hold heavy fastening loads, or as spacers and levelers.
As a screw is tightened, these metric washers flatten to add tension to the joint, counteracting fatigue around the joint from small amounts of vibration.
