Hex Cap Screws

Grade 2 Hex Cap Screwshex-cap-screws3

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

Grade 2 fasteners are ideally suited for holding wood pieces together (in combination 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 quenched and tempered for the additional strength necessary for most automotive uses and other applications where strength is a moderate 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

Manufacturers’ identifications are added for traceability

Grade 8 Hex Cap Screwshex-cap-screws7

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

Grade 8 fasteners are then quenched and tempered to superior strength and hardness qualities

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

Manufacturers’ identifications are added for traceability

18-8 Stainless Steel Hex Cap Screws

The most 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 Screwshex-cap-screws6

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
