Caps and lids for hexagon socket head cap bolts

Today, we are going to discuss the "Caps (lids) for hexagon socket head cap bolts".

In the course of designing a machine, there are environments where dust can land on bolt parts. We have put together a collection of caps for hexagon socket bolts that can be used in such cases.

Caps for hexagon socket head cap bolts

As a quick note, below is a list of caps that can be used on hexagon socket head bolts without modification and caps that can be used in counterbore holes. (We have posted the links in the Model section, but we would appreciate it if you could let us know if any of the links are broken.)

Caps that can be used directly on hexagon socket head cap bolts

(1) Misumi: Cover caps for hexagon socket head cap bolts

Mounting method: Push-in
Detachment method: Detachable

feature

Inserts into the hexagonal hole of the hexagon socket bolt and covers the entire head to prevent dust clogging.

Applicable to: M3,4,5,6,8,10,12
Material: Polyacetal (white, black)
Reference models: BTCSW, BTCSB

(2) NBK: Cover cap for hexagon socket head cap screws

basisSame as Misumi's.

Mounting method: Push-in
Detachment method: Detachable

feature

Inserts into the hexagonal hole of the hexagon socket bolt and covers the entire head to prevent dust clogging.

Applicable: M5,6,8,10,12,16,20
Material: Polyethylene (gray)
Model: SCC

Caps for use with counterbores for hexagon socket head bolts

(1) THK: CG/C Cap

Mounting method: Punching
Removal method: prick and pull out (high probability of non-reuse)

Addendum: On the Mechanical Assembly Engineer's blog.CG/C cap actual installation/removal method　is the article, if you would like to check it out.

feature

Cap to be inserted into the counterbore for hexagon socket head cap bolts. Covers the inside of the counterbore to prevent clogging. A wide range of caps are available. Metal version GC caps are also available. The counterbore dimensions must be set for installation.

Applicable: M3,4,5,6,8,10,12,14,16,20,22,24
Material: Special synthetic resin
Reference model: CV/C

Supplement: Counterbore dimensions for use with CG/C caps

THK's CV/C caps are very good, but you need to specify the dimensions of the counterbore where the cover cap will fit. The dimensions are specified in the catalog by the model of the LM guide, so you can use that as a reference to determine the dimensions. (Only for resin type CV/C caps)

In red in the table, d1 is adjusted to general drill hole dimensions. h is adjusted due to S dimensions. For details, please download the table below and check the contents.

Finally.

Today I have summarized as much as I know about caps for hexagon socket head bolts, but if you have any information that is not included here, I would greatly appreciate it if you could let me know.

One of the most important things we do as designers isEasier processing and lower costs　This is the goal of the project, but this zagri is set where it is needed,Designed with the conscious intention of not using a cap (without a counterweight).　Please try to do so.

That's it.
