Metric bolts pricing and costs varies depending on the size, the type, and the quantity desired. Bolts come in metric and standard measurement sizes. American-made products most often use standard size bolts and foreign made products most often use metric size bolts. Some companies, such as construction workers and auto mechanics, use bolts as part of their service or product. Other businesses, such as hardware stores, use metric bolts as part of their inventory.

Businesses purchase metric bolts online, at hardware stores, and direct from manufacturers. A single metric bolt costs as little as a few cents. Bulk quantities of metric bolts can cost more than $1,000, depending on quantity. When looking into metric bolts pricing and costs, consider items for your needs in the fields below:

1. Auto repair shops buy single replacement metric bolts for automotive repairs.

2. Contractors purchase boxes of metric bolts for construction jobs.

3. Hardware stores buy wholesale bulk quantities of metric bolts for resale.

Purchase single metric bolts to make automotive repairs

Automobiles are full of nuts, bolts, and screws. Because U.S. drivers use cars manufactured outside the U.S., mechanics find themselves needing metric fasteners to complete their jobs. The size and type of metric bolts needed depends on the make, model, and year of the vehicle. Because mechanics cannot predict the parts needed, many purchase single bolt types when the need arises. Automobiles use both fully and partially threaded metric bolts.

I recommend: Northland Fasteners sells metric bolts for automotive use. They offer a section in which mechanics select the bolts according to the vehicle make. The most common bolts are hex head and range from $3 to $13 each. Bob's Loose Nuts also sells automotive metric bolts. They offer hex head stainless steel metric bolts of various sizes for $1 each.

Buy metric bolts by the box for building contract jobs

Construction workers often use metric bolts. They complete building jobs and construction projects with metric fasteners. Workers may prefer metric bolts to metric screws because bolts work with a non-tapered nut and are made according to highly precise ISO specifications. Contractors determine the grade of bolt needed by the amount of torque they wish for the bolt to withstand.

I recommend: The Industrial Depot sells boxes of 100 M6-1.0 x 35 bolts for a cost ranging from a little more than $9 to just under $28. Ace Hardware Outlet also sells boxes of 100 metric bolts. They offer Hillman metric hex bolts for about $25.

Look for metric bolts in bulk for resale purposes

Hardware stores and home improvement stores stock metric bolts for resale. Stores want to appeal to many customers by stocking a variety of bolts, such as hex bolts, stainless steel metric bolts, metric flange bolts and metric auto bolts. To have low cost overhead, it is best for these businesses to purchase bulk wholesale metric bolts from metric bolt suppliers. Distributors consider orders and stock the most highly used metric bolt length, thread pitch, and thread length for the largest quantities.

I recommend: Bolt Depot allows for an option of bulk purchasing of 1,000 metric bolts. The bolts range in price from about $170 per thousand to $1,800 per thousand depending on the metric bolt sizes chosen. Big Bolt manufactures metric bolts and sells in bulk. Contact the company for a quote on pricing.

A metric bolt has its length, thread pitch and thread length specified in a metric measurement system. Other specifications for a metric bolt are classes or grades, which indicate the maximum torque that the bolt can withstand. These metric bolt grades are marked on the bolt head or sometimes on the accompanying nuts.

Like other bolts, metric bolts come in a variety of types such as hex, heavy hex, bent, heavy hex structural, hex transmission tower and round head square neck.

Some of the important parameters you must consider before purchasing a metric bolt are:

1. Forces and torques acting on the metric bolt
2. Required dimensions to suit the other parts of the equipment
3. Required quantity
4. Operating environment

Get into metric flange bolts

Metric flange bolts look just like their English-sized cousins. The flange bolt gets its name because it looks as though it has a skirt, or flange, just below the head of the bolt. According to Northeast Fasteners, this skirt 'acts as a means of distributing the clamping load of the bolt across the fastening surface.' The flange of the bolt is like a washer in that it has similar holding power. They can be stainless steel metric bolts. The metric bolt sizes vary.

I recommend: Northeast Fasteners and Imperial Supplies have a wide selection of metric flange bolts you can use in your business.

Learn about metric hex bolts

Metric hex bolts are perhaps some of the most commonly used bolts. They come in various sizes as well as grades and are characterized by heads with six sides. Some hex head bolts have threads running up directly beneath the heads, while others have threads that run only part-way up the body.

I recommend: Brikksen and the Bolt Depot have metric head bolts for your project.

Look into automotive metric bolts

Automotive metric bolts are quite varied. Some are flange bolts, some come with washers, and some may have points like screws. The materials for the bolts vary as well: stainless steel, with finishes of black zinc phosphate and other materials. These bolts are high grade, and highly engineered. Many of the automobiles that use metric bolts are foreign, such as Japanese and German models.

I recommend: Northland Fasteners and Automotive Fasteners are some of the suppliers of metric auto bolts.

Hex bolt

A hex bolt has a head with six sides. It is commonly used in construction and repair jobs and come in many different sizes and specifications. The most popular hex bolts are made from stainless steel, carbon steel or alloy.

I recommend: Bolt Products gives additional information about hex bolts along with how to choose a hex bolt for a particular job.

Heavy hex bolt

If the job requires a larger head, a heavy hex bolt may be the right bolt to select. Although the head is larger, these bolts usually have shorter thread lengths. Heavy hex bolts are generally used in high temperatures or high pressure applications.

I recommend: Check out this picture and review specifications for a heavy hex bolt at Portland Bolt & Manufacturing.

Bent bolt

Bent bolts can be produced with coarse, fine, right-hand or left-hand threads and can be either cut or rolled. In that way, bent bolts can be customized. Bent bolts are made out of carbon, stainless steel, alloy, nickel, copper or aluminum. Bent bolts have thousands of different uses in industrial, military and nuclear settings.

I recommend: Alloy & Stainless Fasteners customize bent bolts. Get a further explanation of bent bolts and pictures of the different types at their website.

Heavy hex structural bolt

Designed for steel-on-steel structural connections, a heavy hex structural bolt is generally very short. These bolts are not intended for general applications.

I recommend: Focus Technology gives a description and picture of a heavy hex structural bolt.

Hex transmission tower bolt

A hex transmission tower bolt is used most often in structural steel joints for heavy construction projects where a regular structural bolt won't hold on strength.

I recommend: Check out the Allied Bolt catalog options for hex transmission tower bolts.

Round head, square neck bolt

Round head, square neck bolts, also called carriage bolts, are inserted into pre-drilled holes. The round head has threading along part of the shank. The square under the head then keeps the bolt from turning as the nut is tightened. Round head, square neck bolts are commonly used in fastening wood and metal parts together as well as sheet metal applications.

I recommend: J.P. Ruklic Screw Company offers a diagram along with body and head diameter, head height, square width and square depth.
