Metallics RSB63 6-32 x 1 in. Round Head Combo Stove Bolt Screws with Hex Nut - Steel Zinc - Each

Nuts are included. Each RSB63 6-32 x 1 inch round head stove bolt ships with a hex machine screw nut sized for machine screw threads, so you are not sourcing nuts as a second line item. The bolts come 100 to a pack.

6-32 right-hand thread at 32 threads per inch is the standard machine screw size used for device mounting and box grounding in the trade, and the RSB63 is made to ANSI B18.6.3 dimensions, so it threads into any 6-32 tapped hole. At 1 inch long it is longer than a typical device screw, which is useful when you are reaching through a plaster ring or a thick wall finish.

No. The RSB63 is not Buy American compliant and is not ARRA compliant, with country of origin listed as multiple. If the specification on your federal, transit or publicly funded project requires domestic fasteners, this one will not pass submittal.

The RSB63 head takes either a flat blade or a #2 Phillips. It is a combo drive, slotted and Phillips in one head, so whichever driver is already on the belt will turn it. The Phillips recess runs 0.149 to 0.162 inch across and 0.084 inch deep; the slot is 0.039 to 0.048 inch wide.

Head width runs 0.24 to 0.26 inch and head height 0.091 to 0.103 inch. That round profile sits proud of the surface rather than flush, so if you need the fastener to disappear into a countersunk hole, a flat head machine screw is the right call instead.

Zinc plating over steel is a mild corrosion coating meant for dry indoor and protected work, which is what this bolt is specified for across electrical, plumbing, heating and air conditioning jobs. For wet exterior exposure or coastal air, use a stainless machine screw instead; zinc will eventually bloom white and rust through.

The steel used is AISI 1006 to 1022 with a hardness of Rockwell B70 to B100 and a minimum tensile strength of 60,000 psi. That is standard low carbon machine screw strength, fine for mounting devices, plates, straps and light fixtures. It is not a structural fastener and should not be substituted for a graded bolt in a load bearing connection.

They come in a clamshell pack of 100 bolts with nuts, and 100 is the order minimum. Other sizes and quantities are available by request.

Size matters for testing. Steel machine screws from No. 6 through 1/2 inch are subject to tensile testing only when they are longer than 1/2 inch or 3 times the nominal diameter. At 6-32 x 1 inch, this bolt falls into the tested range and meets the 60,000 psi minimum tensile load requirement.
