Metallics G5HC48 – Frequently Asked Questions
1) Is the Metallics G5HC48 strong enough for mounting a motor or structural equipment?
It's a Grade 5 medium carbon steel cap screw, heat treated, with 105,000 psi minimum tensile and yield strength and a hardness of Rockwell C19-30. Metallics lists motor mounting to machinery as a primary use, along with automotive and truck repair. For anything calling out Grade 8 or ASTM structural bolting on the drawing, this is not the right bolt.
2) Do these Metallics bolts qualify for a Buy American or ARRA funded job?
No. The G5HC48 is not Buy American compliant and is not ARRA compliant, and country of origin is listed as multiple. For a federally funded project with domestic sourcing requirements, you'll need a domestically produced fastener instead.
3) Can these zinc plated Grade 5 bolts be used outdoors or in a wet location?
The G5HC48 is steel with a zinc finish, which handles indoor and sheltered use and gives light corrosion resistance. Zinc plating is a sacrificial coating, not stainless, so for constant wetting, coastal air, or direct ground contact you want a hot dip galvanized or stainless fastener instead.
4) How many bolts come in a box of Metallics G5HC48, and can I buy just a few?
They ship as a box of 25, and 25 each is the order minimum, so the box is the smallest quantity. Metallics notes other sizes and quantities are available by request.
5) Do the Metallics G5HC48 bolts come with nuts or washers?
No. The G5HC48 box contains 25 hex cap screws only. Nuts, flat washers, and lock washers are ordered separately, and for a Grade 5 bolt you'd normally pair a Grade 5 (Grade 2H or equivalent marked) 1/2-13 nut to match the thread and strength.
6) What steel are Metallics Grade 5 hex cap screws made from?
Material is carbon steel in the AISI 1008 to 1026 range, heat treated to reach Grade 5 properties. That's why it lands at Rockwell C19-30 rather than the softer unhardened range you get with a Grade 2 bolt.
