OK-VISE low-profile clamps expand when they are tightened down, simultaneously pressing the workpieces against the guide and preventing their movement. They are designed to fit between workpieces and take up very little space on the fastening base. Small in size, yet with an excellent clamping force of up to 150 kN, these clamps guarantee a holding capacity that clearly exceeds the load of machining forces. Fastening with only one bolt ensures quick set-up times.
Our low-profile clamps work just as well on single machines as in large Flexible Manufacturing Systems. In most straightforward applications, the only additional investment needed are the fixed stoppers.
OK-VISE clamps are a reliable basic component of any workholding and fixturing system.
Take a look at this video of OK-VISE clamp types:
Low-profile clamp jaw types
OK-VISE low-profile clamps are available with various jaw types:
Serrated jaws, smooth jaws, grip jaws, machinable jaws, additional piece models and self-aligning models
Additionally, there are several types of pull-down models and one type made from stainless steel.
Four different sizes
OK-VISE low-profile clamps come in four different sizes (A, B, D, F) for metric bolts (M5, M8, M12, M16), while the D-Series Inch Model is made for a half-inch bolt.

|Additional piece models||BK2-VT-T||DK2-VT-T||DK2-VTI-T||FK2-VT+5|
|Self-aligning model, two jaws||BK2-VT-E||DK2-VT-E||DK2-VTI-E||FK2-VT-E|
|Single-wedge pull-down, serrated||BK2-VT-PD||DK2-VT-PD||DK2-VTI-PD||FK2-VTI-PD|
|Double-wedge pull-down, serrated||DK2-WT||DK2-WTI||FK2-WT|
|Double-wedge pull-down, smooth||DK2-WT-S||DK2-WTI-S||FK2-WT-S|
|Stainless steel model||BK2-VT-SS|
|Economy-series, serrated jaws||BK2-VT-O|
|Economy-series, smooth jaws||AK2-VT-SO||BK2-VT-SO|
|Metric bolt size||M5||M8||M12||M16|
|Imperial bolt size||3/16"||5/16"||1/2"||5/8"|
|Force up to (kN)||10||25||90||90||150|
|Force up to (lbs)||2 200||5 600||20 000||20 000||33 000|
|AMin...AMax (mm, compared to optimum)||-2.9...+ 2.5||-1.9...+3.0||-3.3...+5.2||-4.9...3.3|
|Bolt offset (mm)||2 x 0.7||2 x 1.2||2 x 1.1||2 x 1.7|
Normally the end of the code is describing the jaw type, for example -T stands for a model with two additional pieces.
Self-aligning models (-B) have two types of jaws, smooth and serrated.
D-series clamps are also designed for a half-inch bolt. The center hole of the inch-series wedge is wider in order to fit the half-inch socket head screw.
In inch models last part of the code is -VTI ( instead of -VT in metric models).
You can order also low-profile clamps where jaws are not the same type - even if they might not be standard products.
If both jaws of the clamp are the same, typically there is one letter in the end of the code ( like DK2-VT-T has two addtional piece jaws ).
If jaws are different, there are in most cases two letters in the end of the code ( like BK2-VT-SR has one smooth jaw and one serrated )
Same way clamps BK2-VT-BT and DK2-VT-BT posses one self-aligning jaw ("B") and one jaw for addtional piece ("T")
