Metallics SW75B – Frequently Asked Questions
1) What bolt size do Metallics SW75B flat washers fit?
The SW75B is a 3/8 inch flat washer, so it is sized for 3/8 inch bolts, machine screws, threaded rod and anchors. It is a plain flat washer, not a lock or belleville washer, so it spreads bearing load under the nut or head and protects the mounting surface rather than resisting loosening.
2) Are these 3/8 washers plated for corrosion resistance?
They are zinc plated steel. Zinc plating handles dry indoor and protected electrical work, strut and panel mounting, and general MRO fastening. For sustained outdoor exposure, washdown areas or coastal sites, specify stainless or hot dip galvanized instead.
3) How many washers come in a box of Metallics SW75B?
One box holds 5,000 pieces of the 3/8 inch zinc plated flat washer, packed as a box, and the full carton weighs 51 lbs. That is bulk quantity intended for a shop or crib stock rather than a single job, so order by the box with that weight in mind for shelving and handling.
4) Will a 3/8 flat washer keep a bolted connection from vibrating loose?
No. The SW75B is a plain flat washer, which distributes load and protects the surface but does nothing to resist loosening. If vibration is the concern, pair it with a split lock washer, a tooth lock washer, or a nylon insert lock nut on the 3/8 fastener.
5) What part number do I order for 3/8 inch zinc flat washers from Metallics?
Order Metallics SW75B. That part number is the 3/8 inch steel zinc flat washer in the 5,000 piece box, and it is the only configuration offered under that number.
6) What are the carton dimensions on the 5000 count box of 3/8 flat washers?
The box measures 9 x 9 x 6.13 inches and weighs 51 lbs. Dense for its size, so plan a lower shelf or a bin rather than an overhead rack in the parts room.
7) Is the Metallics SW75B washer made to an ANSI dimensional standard?
The 3/8 zinc plated flat washer is listed to ANSI, so the inside and outside diameters follow the standard dimensional pattern for a 3/8 flat washer. That matters if you are mixing stock from more than one supplier across a facility and need the washers to sit the same under the nut.
