Kindorf H113O – Frequently Asked Questions
1) Will a 3/8-16 bolt thread into standard Kindorf channel nuts and strut fittings?
Yes. The H113O is a 3/8-16 hex head cap screw, and that thread pitch is what Kindorf channel nuts, brackets and strut fittings are tapped for. If the nut in your channel is 1/2-13, this bolt will not engage it, you need the larger diameter instead.
2) Are these plain steel or plated? Can I use them outdoors or in a damp location?
The H113O is steel, and steel is also what the finish is given as, so treat it as an unplated bare steel fastener suited to dry interior support work. For wet, exterior or corrosive locations, specify a zinc plated or stainless fastener instead. A zinc plated option in this family of bolts is the Minerallac 1/2-13 hex head bolt, though that is a larger thread and not a drop-in for 3/8-16 channel nuts.
3) What is the difference between the Kindorf H113O hex head bolt and the Minerallac 1/2-13 hex head bolt?
The Kindorf H113O is a 3/8-16 x 1in steel hex head bolt supplied 100 to a pack, sized for channel and strut hardware assemblies. The Minerallac P481348 is a 1/2-13 hex head bolt in Grade 2, zinc plated. The two differ in thread diameter and pitch, so they are not interchangeable in the same channel nut or tapped fitting: a 3/8-16 channel nut takes the H113O, while a 1/2-13 hole or nut takes the Minerallac bolt. The Minerallac is also zinc plated where the H113O is steel.
4) How many bolts come in a box of Kindorf H113O?
They ship 100 to a pack. That is a job-lot quantity for a contractor racking conduit or hanging multiple supports, not a single replacement fastener.
5) What do I need to order with the H113O to complete a channel connection?
The bolt is supplied on its own. A channel or strut connection also needs the mating 3/8-16 channel nut or tapped fitting, and a washer where you are clamping through a slot. Order those separately.
6) Which hex bolt should I specify if the job calls for a zinc plated finish?
The Minerallac P481348 hex head bolt is specified zinc plated, in 1/2-13 thread and Grade 2. The Kindorf H113O is a steel bolt in 3/8-16 x 1in. If the finish callout drives the selection and the hardware is 1/2-13, the Minerallac matches; if the assembly is 3/8-16 Kindorf channel hardware, the H113O is the bolt that fits the thread.
7) What size socket or wrench drives these bolts?
The H113O has a six sided hex head, so it drives with an open end wrench, box wrench or socket rather than a screwdriver or hex key. That matters when you are tightening fittings up tight to a ceiling or inside a rack where there is little room to swing a tool.
8) Is the Kindorf H113O the right fastener for mounting panels and equipment to strut racks?
Yes, it is used for panel and equipment mounting hardware, conduit hangers and rack assembly as well as general bracket mounting on Kindorf channel. The limit is length: 1 inch of shank, so the combined thickness of what you are bolting through has to leave enough thread for the nut to grab.
