Metallics JG8LW177 – Frequently Asked Questions
1) Will a 7/16 inch lock washer work on 1/2 inch threaded rod for hanging electrical equipment?
No. The 7/16 inch size will not pass over 1/2 inch rod. Most electrical hanging and strut work runs 3/8 or 1/2 inch rod, so confirm the rod diameter before ordering this jar; 7/16 inch is more common in machinery and equipment bolting than in rod hanging.
2) How many 7/16 inch lock washers come in a jar of Metallics JG8LW177?
Each jar holds 100 pieces, packed in a jar rather than a bag or box, which is why the shipping weight comes to 1.98 lbs. For MRO stockrooms that is a sensible bin quantity for one bolt size.
3) Are these 7/16 inch lock washers plated for corrosion resistance?
They are steel with a zinc plating. That handles dry indoor and normal protected electrical work, like strut, panel mounting, and equipment anchoring. For wet, outdoor, or washdown locations specify a stainless or hot dip galvanized washer instead, since zinc plating is a thin coating.
4) What is a Grade 8 split lock washer used for instead of a standard one?
Grade 8 is the hardened, higher strength class, matched to Grade 8 bolts and high clamp load joints where a softer washer would flatten and lose its spring. The JG8LW177 is a Grade 8 split lock washer in 7/16 inch, intended to resist loosening from vibration under those loads. If you are bolting light sheet metal with Grade 2 or 5 hardware, a standard split lock or a flat washer is the usual pick.
