Product Overview of Space Saving Bolts

Ultra low head hex socket bolts, Space Saving Bolts are special bolts developed to reduce the height space of the screw head. It is not necessary to process countersinking on the mating materials like flat head bolts.

Product Feature of Space Saving Bolts

Feature of Space Saving Bolts 1: The thickness of the screw head is relatively thinner than that of standard screws, and it is mainly used in some small equipment with high space-saving requirement.
Feature of Space Saving Bolts 2: For SCM435 material, strength class is up to 10.9.
Feature of Space Saving Bolts 3: According to the actual design needs, the thread length can be freely specified in the range.
Feature of Space Saving Bolts 4: Screw material is SCM435 only.
Feature of Space Saving Bolts 5: Most of the models are in stock, allowing same-day shipment.

Mechanism name of Space Saving Bolts:
Stackable workpiece fixture.

Mechanism function of Space Saving Bolts:
Fixture used to fix the workpiece before the bonding material is hardened.

Role of ultra short head hex socket bolts:
After the ultra short head hex socket bolts are used, the four points can be in a plane, and the thickness of the bolt head is thinner, which saves counterbore space and allows stacking on top.

Precautions of Space Saving Bolts

① Space Saving Bolts As the head height decreases, the strength also decreases accordingly.
② One type of material is available: SCM435.
③ The recommended tightening torque varies with the material and the screw diameter. Note that the tightening torque should not be too large, otherwise screw slippage will occur.
  For detailed parameters, refer to overview of space-saving bolts, Space Saving Bolts.
④ For the surface treatment of CBSA type, there may be slight difference in color depending on the batch.
