PRODUCT SPECIFICATIONS

Ruland MSC-4-SS is a set screw shaft collar with a 4mm bore, 8mm OD, and 5mm width. It is commonly used for guiding, spacing, stopping, and component alignment in light duty applications where the collar is infrequently repositioned or removed. Holding power is derived from the screw as it is tightened onto the shaft. In order for the collar to obtain maximum holding power the shaft must be softer than the material of the screw. Proprietary processes have been developed by Ruland to maintain superior fit, finish, and holding power. MSC-4-SS is stamped with the Ruland name and bore size for ease of identification. The forged screw tests beyond DIN 912 12.9 standards to ensure maximum holding power. The use of forged stainless steel hardware has the additional benefit of work hardening resulting in stainless steel with elevated hardness and performance. MSC-4-SS is manufactured from solid bar stock sourced from select North American mills and machined to a fine burr free finish. Ruland uses 303 stainless steel with hardware of like material for consistent corrosion resistance. MSC-4-SS is RoHS3 and REACH compliant and manufactured in our Marlborough, MA factory under strict controls using proprietary processes.
