## Overview

This pack of 100 Alloy Steel Socket Cap Screws features a black oxide finish and internal hex drive, meeting DIN 912/ISO 898 standards.

## 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

### ⭐ 1.0 out of 5 stars







  
  
    Beware, these are not fully threaded
  

*by C***B on Reviewed in the United States on September 27, 2013*

I spent a frustratingly long time trying to find the screws I needed. This listing explicitly specifies "fully threaded" for every diameter and length. I bought M3 and M4, neither of which are fully threaded. I'm sure they are fine screws but neither box of bolts I purchased can be used for the application I bought them for.
