About Socket Head Screws

Alloy Steel Low-Profile Socket Head Screws
Made of alloy steel, these low-profile screws are nearly twice as strong as their stainless steel counterparts. With half the height of a standard socket head, these low-profile screws fit in tight spaces, but are weaker than standard socket heads. Length is measured from under the head.
Zinc-plated steel screws have a zinc outer layer that protects the steel under it from rust, extending the life of the screw.
Class 8.8 steel screws are medium-strength, so they’re strong enough for use with most machinery and equipment. Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. DIN screws meet international standards for materials and dimensions.

18-8 Stainless Steel Low-Profile Socket Head Screws
Nearly as strong as steel, these stainless steel screws won’t rust in outdoor, washdown, and other corrosive environments. With half the height of a standard socket head, these low-profile screws fit in tight spaces, but are weaker than standard socket heads. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch. DIN screws meet international standards for materials and dimensions.

Super-Corrosion-Resistant 316 Stainless Steel Low-Profile Socket Head Screws
More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. They may be mildly magnetic. With half the head height of a standard socket head, they fit where space is limited, but their low profile makes their head weaker. Not recommended for critical fastening applications. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.
Screws that meet DIN 7984 comply with specifications for dimensional standards.

Alloy Steel Ultra-Low-Profile Socket Head Screws
Made from alloy steel, these screws are nearly twice as strong as stainless steel ultra-low-profile screws. Their black-oxide finish provides mild corrosion resistance in dry environments. To fit in the tightest spaces, they have a head that's about one-third the height of a standard socket head, but their low profile makes their head weaker. Not recommended for critical fastening applications. Length is measured from under the head.
Coarse threads are the industry standard; choose these screws if you don’t know the pitch or threads per inch.

Fixture Clamps
Hold a workpiece securely from the side with minimal contact, leaving more of the workpiece free for machining. Thread the clamp into a tapped hole and give the center screw a half turn for quick clamping.
