What is the difference between bolts and screws?

Bolts:

Bolts are generally larger and feature a blunt end without a pointed tip. They are designed to be used with a nut for secure fastening. 

Bolts are commonly employed in applications where disassembly is frequent or where a high clamping force is required. 

They come in various types, including hex bolts, carriage bolts, and eye bolts, each tailored to specific needs. 

Bolts are often used in construction, automotive, and machinery industries.

Screws:

Screws, on the other hand, have a pointed tip and are designed for use without a nut. 

They are intended to be inserted directly into a pre-tapped hole or a material, creating their threads as they are turned. 

Screws are versatile and come in different types such as wood screws, machine screws, and self-tapping screws. 

They are commonly used in woodworking, electronics, and general fastening applications.

Key Differences:

Head Type:

Bolts have a flat or rounded head designed to accommodate a wrench or socket for tightening.

Screws have a variety of head types, including flat, pan, round, or hex, designed for different driving tools like screwdrivers.

Usage of Nut: 

Bolts require a nut for tightening and are used in conjunction with other fastening elements.

Screws are self-contained and do not typically require a nut.

Fastening Approach:

Bolts fasten objects together through the use of a nut on the opposite side of the material.

Screws are directly threaded into the material they are fastening.

Applications:

Bolts are commonly used in structural applications, machinery, and situations where disassembly is necessary.

Screws find applications in woodworking, metalworking, electronics, and general fastening tasks.

Understanding the distinctions between bolts and screws is essential for choosing the right fastener for a given application, ensuring optimal performance and structural integrity.
