Woodruff keys serve as a fail-safe that prevents the shearing of expensive parts exposed to extreme stresses.Woodruff keys are available in various materials and key stock, ranging from high-carbon steel to stainless steel. They're fitted into the woodruff keyseat, which is a half-moon slot cut into the rotating shaft, with a keyway or a Woodruff cutter.
The diameter of a half-round key is usually smaller than the shaft's diameter to fit into the semicircular keyway on the shaft.
Half-round keys can be used for torque transmission in one direction, as their shape only allows sufficient contact area in one orientation.
Due to their shape, half-round keys require careful alignment and positioning during installation.

Precisely align machine parts and prevent movement during assembly. These dowel pins are machined to tight tolerances and have a uniform diameter for a snug fit. They can also be used as a pivot, shaft, or hinge to join moving components. Since dowel pins can be hard to remove, they are best suited for permanent fixtures that don't require frequent adjustments or disassembly.
High-Strength Steel And Stainless steel can also be Customized

Precisely align, level, and adjust spacing on fasteners, shafts, and machinery with these shims.

For accurate leveling, choose materials such as steel or stainless steel, which are hard enough to resist scratching and deforming. Softer shims, like copper or aluminum, can be used as wear plates between components that rub together, preventing damage to equipment.

Spring steel shims are comparable in strength to carbon steel shims, but are harder and hold their shape better. They aren't as corrosion resistant as other shims

Open these rings, pass them over the end of a shaft, and release to spring into the groove. Ring ID is measured with the ring uninstalled. Use retaining ring pliers (sold separately) to install and remove rings.

spring steel rings are an economical choice with good strength. A black-phosphate finish is mildly corrosion resistant in dry environments. In wet environments, a zinc yellow-chromate plated finish has some corrosion resistance, and a zinc chromate plated finish has good corrosion resistance.

DIN 1.4122 stainless steel rings withstand wear caused by abrasion, similar to 400 series stainless steel. They also resist corrosion in wet environments.

Thrust load capacity, also known as PR, is based on using a shaft that is harder than the ring.

Made from black-oxide steel, these adapters resist corrosion in dry environments. Thread length is the same on both ends.

Use the unthreaded end as a pivot point, hinge, shaft, or locator pin. Made from 18-8 stainless steel, Screw the threaded end of these metric studs into a tapped hole and use the unthreaded end as a pivot point, hinge, shaft, or locator pin. All can be installed and adjusted by hand or with a slotted screwdriver. These studs are steel for strength and wear resistance. They’re best for dry environments, since moisture will cause them to rust. All meet ISO 2342 (formerly DIN 427), an international standard for fastener dimensions

The GB9074.8 Cross Recessed Small Pan Head Screw is a precision-engineered fastener designed for applications requiring a flush finish and high torque retention. The small pan head provides a compact and neat appearance, making it ideal for aesthetically sensitive areas. Combined with a single coil spring lock washer, it offers superior vibration resistance and anti-loosening properties. The plain washer serves as a spacer and distributes the clamping force evenly. This assembly is available in various materials and finishes to suit a wide range of applications, from electronics to automotive and beyond

Made from Grade 5 steel, these screws are suitable for fastening most machinery and equipment. Dimensions meet ASME B18.2.1 specifications. Grade 5 steel hex head screws are marked with three radial lines. Length is measured from under the head.
Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments. Black corrosion-resistant-coated steel screws resist chemicals and salt spray per ASTM B117. T Screws that meet ASTM A449 or SAE J429 comply with specifications and testing requirements for material quality.
Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

Alloy Steel Socket Head Screws With a tensile strength of 170,000 psi, these alloy steel screws are stronger than Grade 8 steel screws. Length is measured from under the head.

Black-oxide steel screws are mildly corrosion resistant in dry environments. Zinc-plated steel screws resist corrosion in wet environments. The screws with a blue-dyed finish are easy to distinguish. Zinc-flake-coated steel screws are 20 times as corrosion resistant as zinc-plated screws and comparable to Dacromet-coated screws.

Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance. They are not compatible with coarse threads

Choose these Class 10.9 steel screws for high-stress applications, such as valves, pumps, motors, and automotive suspension systems. They are at least 25% stronger than medium-strength steel screws. Dimensions meet ISO (formerly DIN) or DIN specifications. Length is measured from under the head.

Steel screws should be used in dry, noncorrosive environments. Zinc yellow-chromate plated and zinc-plated steel screws resist corrosion in wet environments. Blue-dyed screws are easy to distinguish. Black corrosion-resistant coated steel screws resist chemicals and withstand 1,000 hours of salt spray. To maintain corrosion resistance, use these screws with black ultra-corrosion-resistant-coated nuts and washers.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

These Class 8.8 steel screws are suitable for fastening most machinery and equipment. Dimensions meet ISO (formerly DIN) or DIN specifications. Length is measured from under the head.

Zinc-plated steel screws resist corrosion in wet environments. Black corrosion-resistant-coated steel screws resist chemicals and withstand 1,000 hours of salt spray. To maintain corrosion resistance, use these screws with black ultra-corrosion-resistant-coated nuts and washers.

Match the thread spacing of mating components. Coarse threads are the industry standard; choose these screws if you don’t know the pitch. Fine and extra-fine threads are closely spaced to prevent loosening from vibration; the finer the thread, the better the resistance.

Screws that meet SAE J1199 comply with specifications for material standards.

Aluminum alloy body with protective sleeve, effectively preventing slippage on all oils in the repair shop. Compared to typical standalone aluminum alloy bodies on the market, it provides reduced vibration during use.
