Stainless Steel Washer -- GN 6341-NI	Specification Washer body: Stainless steel, European Standard No. 1.4305 (American Standard Series 303), matte shot-blast finish Information GN 6341-NI washers are used mainly in mechanical machine and jig construction when...
Steel Washer -- GN 6341	Specification Washer body: Steel, turned Type BT - Blackened finish Type ZB - Zinc plated, blue passivated All types available with cylindrical bore (Type A) or bore for countersunk screw...
GN 350.2	and linking operations. The spherical washer allows precise installation of two non-parallel planes at a required gradient up to ~4°.
HDCW SCW	black oxide finish
GN 184	Countersunk washers GN 184 are retained to the face of the shaft end with a countersunk head screw forming a clean-look end cap. A typical application example would be the...
GN 184.5	Countersunk washers GN 184.5 are retained to the face of the shaft end with a countersunk head screw forming a clean-look end cap. A typical application example would be the...
DIN 6319 C	DIN 6319-NI metric size stainless steel two-piece spherical washers TPSWS inch size steel or stainless steel two-piece spherical washers DIN 6319 G steel dished washers GN 350.3 / GN 350.3-NI...
DIN 6371	DIN 6371 captive C-washers transfer the clamping force of the screw or nut to the workpiece. After releasing the screw thread they can be positioned away from the clamping point.
BN 791 BN 792	For use with hex cap and machine screws. When the screw is tightened, the serrations crunch into the mating faces which prevents the screw from loosening up due to vibrations,...
FWS	FWS flat washers are machined from solid bar. Washers are all ground flat and parallel.
GN 183	GN 183 C-washers may be installed without the removal of the nut from the stud.
GN 185	GN 185 countersunk washers are used for shrouding screw joints when a visually appealing finish is desired. Plastic disks are supplied as a standard item to avoid damage to finished...
GN 350.3 / GN 350.3-NI	GN 350.3 spherical leveling washers were designed to match GN 350 and GN 350.1 leveling sets. The two spherical washers are used together and cannot be detached from each other.
GN 6341	GN 6341 washers are used mainly in mechanical machine and jig construction when DIN 125, DIN 9021 and DIN 6340 washer do not meet requirements.
DIN 127B	Helical spring washer without jaws
DIN 6340	Measurements to DIN; however
TPSWS	Precision machined with all sharp corners removed
DIN 6798A	Serrated Lock Washers
DIN 6319-NI	Spherical washers DIN 6319-NI in stainless steel are used for clamping on non-parallel surfaces (see sketch above) in corrosion-free environments. See also: DIN 6319-NI metric size stainless steel two-piece spherical...
GN 6339	The effect of a washer on the quality of a threaded connection is often underestimated. GN 6339 washers provide a high quality connection. High static clamping force can be achieved...
DIN 6319 G	Their large diameter makes them suitable to use over slots. See also: DIN 6319-NI metric size stainless steel two-piece spherical washers TPSWS inch size steel or stainless steel two-piece spherical...
MB	to secure bearings onto a shaft.
DIN 6319 D	washers and only to be used where full surface contact is assured, i.e. never used over slots. These washers serve to transmit clamping forces in cases where the clamping elements...
RO1-2 RO3-4	Washers are sold as a set.
