Product Overview of Space Saving Bolts
Due to its thinner head, it can also be used to fix the appearance panel, more beautiful than standard bolts.
Product Feature of Space Saving Bolts
Feature of Space Saving Bolts 2: The thickness of the screw head is larger than that of standard screws, which can save a lot of space and reduce weight. It is mainly used in some small equipment that have high requirements on space or require lightweight.
Feature of Space Saving Bolts 3: The material is SCM435 and the heat treatment for thread strength is grade 10.9. The head is very thin, but the head strength grade can reach 5.8.
Feature of Space Saving Bolts 4: According to the actual design needs, the thread length can be freely specified in the range.
Feature of Space Saving Bolts 5: All models are in stock, allowing same-day shipment.

Example Use 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.
