About Hex Head Screws and Bolts

High-Strength Metric Class 10.9 Steel Hex 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.

Metric High-Strength Steel Heavy Hex
Head Screws for Structural Applications

Designed for construction and exterior building applications, these metric screws are often used to join I-beams and scaffolding. Their partial threading leaves an unthreaded portion that is strong enough to stand up to the sideways forces of joints.

High-Strength Metric Class 10.9
Steel Flanged Hex Head Screws

These metric screws are at least 25% stronger than medium-strength steel screws. Use them in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. The flange distributes pressure where the screw meets the surface, so there's no need for a washer.

JIS High-Strength Steel Flanged Hex Head Screws

Made to Japanese Industrial Standards, these Class 10.9 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. The flange eliminates the need for a washer.

Alloy Steel Low-Profile Socket Head Screws

Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces.

Metric Alloy Steel Flanged Button Head Screws

These metric alloy steel screws are nearly twice as strong as stainless steel button head screws. They have a flange that distributes pressure across a wide surface, eliminating the need for a separate washer.

Hex Head Screw Assortments

These assortments include hex head screws and hex nuts.

T-Slot Bolts

For quicker setups than a separate T-slot nut and stud, slide these bolts into T-slot tracks on machine tool tables.
