With the strength of steel and the corrosion resistance of 18-8 stainless steel, these 17-4 PH stainless steel screws are suitable for high-strength fastening in corrosive environments.

Our most corrosion-resistant metal screws, titanium screws withstand salt water, acids, and chemicals. They have a high strength-to-weight ratio—stronger than medium-strength steel screws and about 40% lighter.

Aluminum screws are one-third the weight of steel and have good corrosion resistance.

Ceramic screws won't melt, rust, seize, or become brittle—even at extreme temperatures. They are nonconductive and highly resistant to corrosive gases.

Brass screws are electrically conductive, nonmagnetic, and have good corrosion resistance.

Made from 316 stainless steel, these Grade B8M screws are more corrosion resistant than 18-8 stainless steel screws and have excellent resistance to chemicals and salt water. Screws meet ASTM A193 regulations, so they can be used in high-pressure and high-temperature applications. Also known as pressure bolts.

The most common heavy hex head screw, these steel screws meet ASTM A325 regulations for structural joints, such as mating I-beams and scaffolding.

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.

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.

Comparable in strength to Grade 9 screws, these are about 20% stronger than high-strength steel screws and often used in heavy duty applications, such as stamping and earth-moving equipment. The flange eliminates the need for a washer.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. The flange distributes pressure where the screw meets the surface, eliminating the need for a washer.

These screws are chemical and oil resistant, nonconductive, and lightweight. The flange eliminates the need for a washer, distributing pressure where the screw meets the surface.

Made from 18-8 stainless steel, these screws have good chemical resistance. A flange under the head distributes pressure over the surface, eliminating the need for a washer.

About 20% stronger than medium-strength steel screws, these Grade 8 steel screws can be used in high-stress applications, such as valves, pumps, motors, and automotive suspension systems. Serrations under the flange provide mild vibration resistance.

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Serrations under the flange provide mild vibration resistance.

Choose these metric screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are about 10% stronger than medium-strength steel screws. Their serrated flange helps to resist vibration.

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. They are over 50% stronger than stainless steel thread-locking screws. For vibration resistance, they have a thread locker bonded to the threads.

Also known as Sems screws, these screws have a permanently attached but freely rotating tooth lock washer that bites into the mating surface for vibration resistance.

Made from 18-8 stainless steel, these screws have good chemical resistance. They have a thread locker to prevent loosening from vibration.

Position components in assemblies, as well as separate or connect parts with these standoffs.

Mount components onto food processing lines, walls, and sanitary equipment while leaving space to clean in between.

A nickel-chrome plating gives these standoffs a mirror-like finish.

Protect components from electrical charges.

A recess under the hex clinches a panel for a strong hold that won't push, pull, or twist out. When mounted with a lever press, the hex sits flush with the surface and the open end creates a through hole.

Thread the male connection into a tapped hole and snap the other end into a panel for a secure hold that can be released for repairs and upgrades.

Designed for multi-level printed circuit board applications, these self-aligning, through-hole supports have a chamfered female end for stacking. The other end snaps and locks in place for a permanent connection.

The ends of these removable supports snap in and compress between panels to reduce vibration of miniature cooling fans in compact electronics.

Secure the self-tapping female connection with a screw; the other end snaps snugly into a panel, yet can be released for repairs and upgrades.

Once the end is clinched in place, panels with keyholes easily slide on and off these supports.

These assortments include hex head screws and hex nuts.

Attach these nuts to rods, pipes, and tubes to make pivoting and hinge movements where misalignment is not a concern.

Adapt your shaft to a threaded end without having to machine threads onto your shaft.
