Flange bolt benefits

Load distribution

Flange bolts help spread weight better than regular bolts. The flange works like a washer and spreads pressure out. This keeps the parts you connect safe from harm. The flange makes the area bigger, so no spot gets too much pressure. This is helpful when things shake or move, like in cars or machines. You can use a flange bolt chart to pick the right size. This helps you get the best weight spread for your project.

The flange makes the bolt hold tighter and not come loose. It works great when things move or shake a lot.

耐振動性

Flange bolts stay tight when things shake more than normal bolts. The flange keeps the bolt from getting loose when things move. This is important in cars, big machines, and plumbing. For example, exhaust flange bolts stay tight in engines that shake a lot. Tests show flange bolts keep their grip longer than regular bolts. This means you do not have to worry about bolts coming loose.

• Sensors and computer tests show flange bolts handle shaking well.
• Tests show flange bolts stay tight after lots of shaking.

Easy installation

Flange bolts save time because you do not need a washer. You have fewer parts to use, so work goes faster. Workers find flange bolts easy to put in, even in small spaces. The flange helps line up the bolt and makes it easier to tighten. You get a strong hold without much work.

• Using flange bolts can make the job one-third faster.
