Metallics SHTB60 – Frequently Asked Questions
1) Is the Metallics SHTB60 bolt stainless steel, and will it hold up outdoors?
It is 18-8 stainless, the common austenitic grade (roughly 18 percent chromium, 8 percent nickel) equivalent to 304. That gives good corrosion resistance for exterior, damp, and wash-down work, which is why it gets specified for outdoor strut and channel runs, pump and equipment mounting, and coastal-adjacent jobs. For direct salt spray or chemical immersion, a 316 fastener is the better call.
2) How many bolts come in a box of Metallics SHTB60?
Each box holds 100 pieces of the 3/8-16 x 4 inch 18-8 hex tap bolt. That is a stocking quantity for an electrical or MRO crib, not a single-job pack, so if you only need a handful for one hanger run you will have plenty left over.
3) Will a 3/8-16 stainless hex tap bolt work with strut channel and 3/8 inch channel nuts?
Yes. 3/8-16 is the standard coarse thread used on 3/8 inch channel nuts and strut hardware, and the SHTB60 is fully threaded along its 4 inch length, so it engages a channel nut at any depth. Pair it with stainless nuts, washers, and channel nuts so you are not mixing stainless with plain or galvanized steel in a wet location.
4) What is the difference between a hex tap bolt and a regular hex cap screw?
A tap bolt is threaded right up to the head; a hex cap screw of the same size has an unthreaded shank under the head. The SHTB60 is the tap bolt version in 3/8-16 x 4, so it suits threading directly into a tapped hole, into a channel nut, or through stacked material where the clamp thickness is not fixed. If you specifically want an unthreaded body bearing in a shear joint, order a hex cap screw instead.
5) Does the Metallics SHTB60 come with nuts and washers?
No. The SHTB60 is bolts only, 100 pieces of the 3/8-16 x 4 inch 18-8 hex tap bolt. Nuts, flat washers, and lock washers are ordered separately, and for this bolt you want them in 3/8 inch 18-8 stainless to keep the joint from galvanic corrosion.
6) What wrench or socket size does a 3/8-16 hex tap bolt take?
A 3/8 inch diameter hex bolt uses a 9/16 inch hex head, so a 9/16 socket or wrench drives the SHTB60. Stainless galls easily when run down hard, so use an anti-seize on the threads if you are torquing into a stainless nut or tapped stainless hole.
