In the new century, business owners are forced to adhere to a mode of economy, so making an accurate estimate without costs is the first task.

This also applies to the counting of fasteners - screws intended for disassembling or combining parts. The screw looks like an elongated piece with an external thread on one side and a head that serves to transmit torque on the opposite side.

The weight of the screws is of decisive importance for the budgeting, for this purpose an online calculator is used. The tool takes into account indicators that allow you to accurately calculate the weight of various types of screws, including semicircular screws.

Screw calculator allows you to calculate how many items is contained in 1 kilogram. The calculator also provides the ability to calculate the weight of the fastener if the number of pieces is known.

Pan-head screw

Calculation parameters

The following indicators are taken into account:

type of fastener: in addition to the round head screw, the weight and number of fasteners with a countersunk head, with a round head, with an internal hexagon are calculated;
standard used for cylindrical and hexagonal screws, countersunk head screws, regulates the rules for manufacturing a semicircular screw with a press washer and with a cross-shaped slot. Also international standards apply to these products: DIN 912, DIN 965 and others;
diameter and length;
used coating: zinc, copper, chrome, the use of anti-corrosion and other compounds;
the strength of fastener, which is calculated based on their mechanical properties. There are 11 strength classes for these fasteners;
number of fasteners.

After entering standard indicators, the system calculates online the amount of fasteners or their weight. If materials that are not made of metal are used, then their coefficient is taken into account.

Pros of using an online calculator

New technologies allow online component counting, which entails significant advantages:

there are no errors in calculating the number of screws, nuts, self-tapping screws and other similar products, since they are carried out by a computer program configured for this type of work; procurement processes are significantly accelerated, which helps suppliers and wholesalers to supply the exact number of components to the site; it becomes possible to work in modern ways, which raises the company's prestige among competitors and customers.

Fasteners calculator is a simple and affordable tool that improves the quality of workflows!
