Metallics BHC145 – Frequently Asked Questions
1) What thread does the Metallics BHC145 hex bolt use, and will it take a standard 3/4-10 nut?
The BHC145 is a 3/4 inch diameter hex bolt with 10 threads per inch, which is standard 3/4-10 UNC coarse thread. Any standard 3/4-10 coarse nut or tapped hole will take it. Measured thread outside diameter runs 0.729 to 0.768 inch. Threads are made to ASME B18.2.1-1996.
2) Are these Metallics hex bolts sold individually or only by the box?
BHC145 ships as a box of 50 bolts, and 50 count is the order minimum, so you are buying a full box rather than loose pieces. Metallics notes other sizes and quantities can be had by request.
3) What size wrench or socket fits the head on this 3/4-10 hex bolt?
Head width across flats measures 1.088 to 1.125 inch, so a 1-1/8 inch wrench or socket is the fit. The head is a standard hex pattern, not a flange or square head.
4) Is zinc plated steel good enough for outdoor or damp mechanical room use?
These are steel bolts with a zinc finish. Zinc plating handles indoor and sheltered damp locations like mechanical and electrical rooms fine, and it is what most interior strut, hanger and equipment anchoring work uses. For sustained outdoor exposure, wash-down areas, or coastal sites, step up to hot dip galvanized or stainless in the same 3/4-10 size instead.
5) What is the exact part number and series to order these Metallics hex bolts under?
Order by Metallics part number BHC145, in the BHC and JBHC hex bolt series. That number is the 3/4-10 x 4-1/2 steel zinc bolt in a 50 count box. Country of origin is China.
6) How heavy is a box of 50 Metallics BHC145 bolts for shipping or carrying up to a roof?
A full box runs 33.11 lbs, so it is a one hand carry but a real load if you are taking several boxes up a ladder. Plan on roughly two thirds of a pound per bolt.
