The Knurled Standoffs permit quick and neat fastening of components, terminal boards, brackets and sub-assemblies in hard-to-get at places without the need for nuts and wrenches, washers or lock pins.
Stainless Steel (SS) The fasteners provide durable threads for strong uniform attachment at all points on panels and chassis of varying thickness and material. Extension E provides additional thread depth for thin panels, without restricting flush mounting at the panel front.
This non-magnetic stainless steel fastener is designed for use in aluminum, mild steel, soft brass and other materials of Rockwell Hardness B-70 or less. Typical holding specifications for 66112- SS-12 in standard chassis aluminum, .062 thick, are: push-out 100 lbs. Threads: Class 2B MIL-S-7742.
Hardened Carbon Steel (S) The fasteners provide durable threads for strong, uniform attachment at all points on panels and chassis of varying thickness and material. Extension E provides additional thread depth for thin panels, without restricting flush mounting at the panel front.
This hardened steel fastener is designed for use in aluminum, mild steel, soft brass and other materials of Rockwell Hardness B-85 or less. Typical holding specifications for 66112-S-7 in standard chassis aluminum, .062 thick, are: push-out 125 lbs., and torqueout 45 inch lbs.
Stainless steel inserts: for use in most aluminums or in low carbon steels that are 1/4 hard or softer.
Steel inserts: for use in low carbon steels that are 1/2 hard or softer and for stainless steel in the annealed condition.
Cadmium Plate Finish (7) for carbon steel and the Passivate Finish (12) for stainless steel is recommended. Material Specifications (see page 289)
