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 Decrement-coated screws. Zinc-aluminum-coated steel screws are 40 times as corrosion resistant as zinc-plated screws and comparable to Magni-coated screws. They withstand 1,000 hours of salt spray per ASTM B117.
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.
Screws that meet ASTM A574, ASTM A574M, and ISO 898-1 comply with specifications and testing requirements for material quality. Screws that meet ASME B18.3, ASME B18.3M, ISO 21269, and ISO 4762 (formerly DIN 912) comply with specifications for dimensional standards.
STAINLESS STEEL HELICAL INSERTS.
STAINLESS STEEL HELICAL INSERTS.
Also known as Heli-Coil inserts, these inserts have coils that expand once installed to securely anchor the insert. All have a prong for ease of installation. An installation tool grips the prong and reduces the coil diameter, enabling the insert to fit in tapped holes. Remove the prong to insert the screw. Installation requires a drill bit, a helical insert tap, an installation tool, and a prong break-off tool.

CLAMPING SHAFT COUPLINGS
CLAMPING SHAFT COUPLINGS
Designed to grip evenly around your shaft, clamping couplings provide more holding power than set screw couplings without marring the shaft. Slide onto the end of your shaft and tighten the clamping screws to secure. Good for high-torque applications, rigid couplings connect two shafts that are aligned, allowing for no relative movement between the shafts.

BEARINGS
All bearings are designed to handle radial loads, thrust loads, moment loads, or a combination of the three. Radial loads are perpendicular to the shaft. Thrust loads are parallel to the shaft. Moment loads are twisting forces that result from offset loads.
KEYWAY BROACHES .
KEYWAY BROACHES .
Cut precision keyways. Each tooth’s cutting edge is a few thousandths of an inch larger than the one before. The cutting edges increase until they reach the required size. Broaches are for use in hand and hydraulic arbor presses and are great for maintenance and short-run production operations.

SUPPORT-RAIL SHAFTS.
SUPPORT-RAIL SHAFTS.
These shafts include a support rail for a stable setup that eliminates bending and prevents linear bearings from rotating. Shafts have a smooth surface to reduce friction and wear on linear bearings—the lower the micro inch value a shaft has, the smoother its finish and the less friction it will create. They are case-hardened to increase hardness and wear resistance on the surface of the shaft while allowing the center to remain soft for absorbing stresses caused by shifting loads. The edges are chamfered to remove sharp corners, reducing damage to bearings, housings, and other components during installation. All are turned, ground, and polished to tight diameter and straightness tolerances.
