Cleaned and double bagged in an ISO Class 5 (Fed. Std. Class 100) clean room, these screws are ready to use on chambers and components in high-vacuum systems.
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.
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.
More corrosion resistant than 18-8 stainless steel screws, these 316 stainless steel screws have excellent resistance to chemicals and salt water. Use these low-profile screws where space is limited.
With a head one and a half times taller than a standard socket head, these screws are easier to install in deep counterbored holes and other hard-to-reach places.
Fasten these screws inside a high-vacuum system without bringing in contaminants.
No need for separate bits—these screws lock directly onto square-drive socket wrenches, reducing the risk of dropping parts during installation.
Taller than cheese head screws, these have a deep drive to maximize driving power and a narrow diameter to fit in tight spaces.
These screws have good chemical resistance.
More corrosion resistant than 18-8 stainless steel screws, these screws have excellent resistance to chemicals and salt water.
A zinc plating provides mild corrosion resistance.
Brass screws are corrosion resistant in wet environments, nonmagnetic, and electrically conductive.
Made from nylon, these screws are chemical and oil resistant, nonconductive, and lightweight.
When head height is important, these screws fit into spaces where other wide head screws won't fit. Also known as shutter screws, their ultra-wide truss head distributes the load over a large area for excellent holding pressure.
Fit these metric screws into spaces where head height is important and other wide head screws won't fit. Also known as shutter screws, they have an ultra-wide truss head to distribute the load over a large area for excellent holding pressure.
Wire these screws together through the hole in the head for better vibration resistance than any other rounded head screw.
Difficult to remove without special tools, these screws have three grooves.
Also known as pancake head screws, these have a head that is about two-thirds the height of standard rounded head screws.
Cutting wings under the head allow plastic to expand and contract without cracking. A washer made from aluminum and rubber bonded to steel adds a watertight seal.
With a reduced head size and an unthreaded shoulder, use these screws as a shaft or dowel pin for small rotating parts in low-clearance applications.
The head height of these screws is about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.
These metric screws have a head height that's about two-thirds the head height of a standard shoulder screw. Use them in low-clearance applications such as inside machines.
With a shoulder that’s twice as precise as standard shoulder screws, these metric shoulder screws act as a shaft or axle for bearings and other moving parts in applications that require smooth and accurate movement, such as measuring and lab equipment. Made of 18-8 stainless steel, they’re nearly as strong as steel but won’t rust in outdoor or washdown environments.
Made from 18-8 stainless steel, these thumb screws are chemical resistant. They have a thin, knurled head for use in low-clearance applications.
These slotted thumb screws have a thin, knurled head for use in low-clearance applications. Made of 18-8 stainless steel, they are chemical resistant.
These metric thumb screws are made of chemical-resistant 18-8 stainless steel. They have a thin, knurled head for use in low-clearance applications.
These metric thumb screws have a thin, knurled head for use in low-clearance applications. They have a black-oxide finish to resist corrosion in dry environments.
A thin, knurled head allows these thumb screws to be used in low-clearance applications. They have a black-oxide finish to resist corrosion in dry environments.
Brass thumb screws are corrosion resistant in wet environments and electrically conductive.
Stainless steel thumb screws have excellent corrosion resistance in most environments.
These steel thumb screws have a black-oxide finish to resist corrosion in dry environments.
A knurled head allows for slip-resistant controlled adjustment.
These metric thumb screws have a knurled head for a slip-resistant controlled adjustment.
Tighten these thumb screws by hand or with a hex key for more torque.
These metric thumb screws are made of chemical-resistant 18-8 stainless steel. Also known as dog- and pilot-point thumb screws, insert the point into a drilled hole or slot to hold items in place.
Made from 18-8 stainless steel, these thumb screws are chemical resistant. Also known as dog- and pilot-point thumb screws, insert the point into a drilled hole or slot to hold items in place.
For maximum contact with angled and uneven surfaces, the tip swivels in all directions. The tip is narrow so it will fit through threaded holes.
A large swivel angle allows these thumb screws to make better contact with angled and uneven surfaces than nonremovable swivel-tip thumb screws.
These nylon thumb screws are chemical resistant, nonconductive, and lightweight.
A thin head allows these thumb screws to be used in low-clearance applications.
Stainless steel binding barrels and screws have excellent corrosion resistance in most environments.
One-third the weight of steel, aluminum binding barrels and screws resist corrosion in wet environments.
An unthreaded barrel allows quick assembly with a press or a hammer.
Brass binding barrels and screws are corrosion resistant in wet environments and electrically conductive.
These barrels and caps are corrosion resistant in wet environments.
Plastic binding barrels and caps are chemical resistant, nonconductive, and lightweight.
Create strong joints in wood and wood composite.
Sealed with PVC foam under the head to prevent leaks and keep contaminants out.
A shallow head makes these bolts good for low-clearance applications.
