Round Posts, Bolt End Threaded, Length and Thread Length Configurable

Round post is a common processing component, with the functions of connection, fastening, support, separation and so on, mainly used in various fastening and supporting mechanisms.
At the same time, there are a variety of materials to choose from, allowing it to be widely used in automation, electronics and electrical appliances, medical treatment, communication and other fields.

Type				Material	Surface Treatment	D(mm)	L(mm)
Both Ends Threaded Type		Both Ends Threaded, Thread Length Configurable
Standard	With Wrench Slot Type	Standard	With Wrench Slot Type
E-NETL	E-NETLS	-	E-NETPS	General Structural Steel or Carbon Steel	-	5 to 50	15 to 1000
E-ETKL	E-ETKLS	-	E-ETKPS		Black Oxide
E-PETL	E-PETLS	E-PETP	E-PETPS		Electroless Nickel Plating
E-SETL	E-SETLS	E-SETP	E-SETPS	Stainless Steel	-

If there are requirements for rust prevention, give priority to products with surface treatment of electroless nickel plating and those made of stainless steel. Please click Rust Prevention Methods
Products made of general structural steel or carbon steel are coated with anti-rust oil.
There may be grinding gloss marks near the wrench slot on products without surface treatment.

Feature 1: the length and thread of the round post can be freely specified to accommodate different operating environments.
Feature 2: 2 types of materials to choose from: general structural steel, stainless steel.
Feature 3: Two types of surface treatments available: black oxide (ferroferric oxide protective film) and electroless nickel plating.
Feature 4: products with surface treatment (electroless nickel plating) and material (stainless steel) for good anti-rust performance are widely used in precision equipment and dust-free environment.
Feature 5: with the main functions of connection, fastening, support and separation, it is often used in mechanisms with various frames as a connection and support component.

(1) Fastening method of post
The post is generally fastened by torque method. For bolts, fasten them within the range of fastening torque, otherwise excessive torque will cause thread fracture.
(2) Anti-rust specification selection and maintenance
. If there are requirements for anti-corrosion performance, select products with surface treatment of electroless nickel plating or those made of stainless steel when choosing general structural steel products.
General structural steel posts without surface treatment are recommended to be stored in a constant-temperature and dry environment, and regularly applied with anti-rust oil for maintenance.
