## Overview

## Description

Socket Cap Screws are reliable and durable and are used in many applications. They are available in a variety of head styles and materials.Alloy Steel is steel that has been alloyed with other materials to improve overall physical properties. Steels are designated by a 4 number SAE Steel grade. The first two digits indicate the primary materials used to form the steel. The last 2 digits identify the percentage of carbon for the alloy (in hundredths). Tensile strength ranges for the alloys typically used in these fasteners range from 170,000 to 180,000 psi (pounds per square inch), making these amongst the strongest of materials.With a high cylindrical head, socket cap head fasteners have a recessed driving area and offer high hold power at high torque levels. Hex socket drive systems are driven by hex wrenches or power tools with hexagonal bits.

## Features

- Socket Cap Screws are durable and reliable
- Alloy Steel is one of the strongest materials used in fasteners, making this an ideal material to use when the primary concern is the application pulling apart
- Socket cap head fasteners are very common in industrial applications
- Drive system is a hexagon-shaped hole
- Coarse threads are better for brittle materials, and will assemble and disassemble more quickly than fine threads

## Customer Reviews

### ⭐⭐⭐⭐ 







  
  
    Seems to be good quality, one minor quibble
  

*by B***B on Reviewed in the United States 🇺🇸 on June 7, 2014*

This was listed as fully threaded, but it actually is only partly threaded as can be seen in the photo with the description if you look closely.  This isn't an issue for my current project, but something that you might be aware of.  Other similar screws that I have are fully threaded.

### ⭐⭐⭐⭐ 







  
  
    Woohoo fully threaded.
  

*by S***D on Reviewed in the United States 🇺🇸 on August 21, 2014*

Works great for my projects. I was a little worried that the 25mm would be partially threaded even though it stated it would be fully threaded like the 50mm one I bought. This one actually was fully threaded and came of plenty of them.

### ⭐⭐ 







  
  
    It not fully threaded!!
  

*by R***H on Reviewed in the United States 🇺🇸 on January 7, 2013*

I don't know if it Amazon or the manufacturer, but this wasn't according to specs.  It said fully threaded on the website, yet it was only partially threaded.  I should have read the label that was on the box.  It has (PT) next to the size.  I made it work for my scenario, but be warned you may get a partially threaded screw if buying these threads.
