Promotional bolt gauges put your company name on the tool a mechanic, maintenance tech or parts counter clerk reaches for every time a loose nut or screw needs a size. Each one is a flat card or plate that sizes fasteners in seconds, so it stays in a toolbox, a shirt pocket or on the shop wall long after the trade show ends.
Which gauge fits your customers
The nut and bolt gauge covers the widest everyday range. It sizes metric fasteners from 3 mm to 22 mm and inch fasteners from #4 to 1", with a thread pitch scale on the back. For heavy hardware, the large diameter nut, bolt and washer gauge reads from 3/4" and 20 mm up to 2" and 50 mm.
Specialty styles cover single jobs. The drill gauge sizes fractional and metric bits and carries a 7 1/2" ruler. The rivet gauge handles #3 to #8 pop rivets, and the terminal gauge sizes battery terminals, starter lugs and ring terminals for auto and electrical work. Three stainless steel screw gauges, each under 5" long, suit buyers who want a metal tool, and the L gauge comes in inch and metric versions.
For a parts counter or service bay, the wall mount thread checker stands 39" tall and uses real steel fasteners to check UNC, UNF and metric threads from 4 mm to 12 mm.
Logos, colors and order sizes
11 of the 12 styles start at 100 pieces, and the wall mount thread checker starts at 2. The plastic gauges come in stock colors such as blue, red and yellow, and the rivet, drill, terminal and large diameter gauges offer a custom color match from 2,500 pieces. The imprint method and logo area vary by style, so check each product page or ask for a free digital proof before you order.
Who orders custom bolt gauges
Hardware stores and fastener distributors hand them out at the counter so customers stop guessing at sizes. Auto parts stores, repair shops and fleet teams use the terminal and drill gauges as practical giveaways, and the gauges sit well beside branded tape measures and tool sets in a contractor kit. Trade schools and safety programs give them to students and new hires who are still learning thread sizes. If your customers work on vehicles, our custom tire pressure gauges are another tool that earns a spot in the glovebox.
