The most basic difference between a cap screw and a bolt is the way in which these fasteners are installed. Technically, a bolt is installed by turning a nut to tighten the fastener, while a cap screw in installed by turning the head of the bolt to assemble and tighten.

Socket screws are the preferred screw when bolts and nuts can't be used. The hex socket means the screw has six stress-bearing sides. Compared 

I have an application that is resulting in failed 7/8" hex head bolts. I'm early in the investigation phase, but have read that a SHCS is stronger than the same size hex head bolt. One reason stated is simply because better alloys are used, which gives them higher minimum tensile strength. Others have said that the design makes them stronger, but no explanation behind that claim.

As a domestic manufacturer, Lightning Bolt stocks a vast inventory of ASTM A193 Grade B7 Studs, including b7 threaded rod, b7 cap screws, and b7 hex bolts and of course the ASTM A194 Grade 2H nuts that pair with them. First off, for those who are unfamiliar with the term, ASTM stands for the American Society of Testing and Materials.

With a tensile strength of 150,000 pounds per square inch, grade 8 hex cap screws are stronger than grade 5. This grade is heated similar to grade 5, but they are fully heat treated versus case hardened. Their strength makes them good candidates for tractor fabrication, suspension applications and other high demand fastening applications. Grade L9

These fasteners are used at high pressures and temperatures. Hex cap screws have a washer face underneath the head and are used in precise applications. Heavy hex head bolts are commonly used to make structural connections in buildings, bridges, and railways. More information Show All 281 Results Steel Heavy Hex Bolts 108 Items

Specification: Hex Machine Bolts are typically governed by A307 Grade A, whereas Hex Cap Screws are governed by SAE J429, Grade 2,5 and 8. Dimensions - Hex Machine Bolts are typically used when the "physical" or "mechanical" properties of performance are more important than the dimensional. This is often the case.

Hex bolts and hex cap screws feature a large fastener head for distributing clamping load. These fasteners are used at high tensions and temperatures.

With a tensile strength of 150,000 pounds per square inch, grade 8 hex cap screws are stronger than grade 5. This grade is heated similar to grade 5, but they
