What are Hex Cap Screw?

Hex Cap Screws are fasteners including a hexagonal, six-sided, head with a washer face on the air surface and a chamfered point. Generally used in construction and machine assemblies, hex cap screws are one of the most shared fasteners used on the jobsite today. Specifications for hex cap screws are described under the ASME B18.2.1-1996 standard. Hex cap screw specifications include ASTM A449 & SAE J429: Grade 2, Grade 5 & Grade 8.

Hex Cap Screws are NOT Hex Bolts

Mistaking a hex cap screw for a hex bolt is a very mutual existence, but the two fasteners differ in many ways, with the way they are used and installed.

Hex bolts are installed by turning a nut to tighten the fastener

Hex cap screws are installed into tapped holes by turning the head to collect and tighten

Hex cap screws feature a washer face on the bearing surface and the chamfered point

Hex bolts have neither the washer face or chamfered point

Hex cap screws are generally used for precision applications where a tight tolerance is essential

Hex bolts are often used in the construction industry where the mechanical properties are more important than dimensional tolerances

Grades of Hex Cap Screws:

Grade 2 hex cap Screws:

Often referred to as “hardware” quality, these fasteners are naturally made of low carbon steel

Grade 2 fasteners are ideally suited for holding wood pieces together (in mixture with appropriate nuts and washers) or general hardware use where higher strength is not required

There is no grade marking on the head of Grade 2 fasteners

Many manufacturers will put a distinguishing company identification on the head

Grade 5 hex cap Screws:

Tempered Grade 5 fasteners are made of medium carbon steel

Grade 5 fasteners are satisfied and hardened for the additional strength essential for most automotive uses and other applications where strength is a modest concern

The grade marking on the head of a Grade 5 fastener is three equally-spaced lines coming out from the center of the head

Grade 8 hex cap Screws:

Tempered Grade 8 fasteners are manufactured of medium carbon alloy steel for the most severe applications

Grade 8 fasteners are then satisfied and hardened to superior strength and hardness qualities

The grade marking on a Grade 8 fastener is six equally-spaced lines coming out from the middle of the head

18-8 Stainless Steel hex cap Screws:

The utmost popular type of stainless used in the production of fasteners

The composition is approximately 18% chromium and 8% nickel, thus the name 18-8

18-8 stainless steel consists of several grades of stainless in this classification including 302, 303, 304 and 305

All of these grades of 18-8 stainless steel have good strength and corrosion resistance

316 Stainless Steel hex cap Screws:

316 stainless steel is more corrosion resistant than 18-8, but also more expensive

316 stainless steel is composed of approximately 18% chromium and 12% nickel with the addition of 2% to 4% molybdenum

316 stainless steel also maintains its strength at higher temperatures than 18-8

410 Stainless Steel hex cap Screws:

410 stainless steel has approximately 12% chromium with no nickel

410 stainless steel is not very corrosion resistant and is magnetic, but it can be heat-treated to become harder
