Grade 4.8-12.9 high strength hexagon socket bolts Galvanized Hot Dip Galvanized Hexagon Bolts
Grade 4.8-12.9 high strength hexagon socket bolts，Galvanized hot dip galvanized hexagon bolts，4.8 Grade Hexagon Head Bolts
Hex bolt: A type of fastener consisting of a head and a screw (a cylinder with external threads), used in conjunction with a nut for fastening two parts with through-holes. This type of connection is called bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection.
1. According to the force mode of connection, there are ordinary and reaming holes. Bolts for reaming holes should fit the size of the holes and be used when subjected to transverse forces.2, according to the head shape of hexagonal head, round head, square head, countersunk head, and so on, the general countersunk head is used in the requirements of the connection after the surface is smooth without protrusions, because the countersunk head can be screwed into the parts. Round heads can also be screwed into parts. The tightening force of square head can be larger, but the size is large. The hexagonal head is the most commonly used.

Plated Drop in anchor Wedge Anchor Bolts Wedge Anchor Bolts
Plated Drop in anchor Wedge Anchor Bolts
Select an alloy drill bit that matches the outer diameter of the internal expansion bolt, drill the hole as deep as you need to install it, and then clean the hole.，Expansion screws must be installed on a relatively hard foundation, soft and easy to fall off the place is unstable, such as the ash seam of the wall. Remember not to screw off the screw to prevent the bolt from falling into the hole when the hole is drilled deep，
The bolt is a new mainstream product of internal thread bolt with large contact area and high pulling strength.
The diameter of the local column ring is smaller than the diameter of the internal thread, so the required pre-hole is smaller and the construction efficiency is improved. The other is convenient for upward construction.
The use of internal cone makes the cone not easy to lose during construction and prevent the occurrence of falling off after construction.
Can process concrete, stone.
Application: suitable for electrical equipment engineering, piping engineering, air conditioning pipeline engineering

Drywall screw with coarse thread and bugle head Bugle Head Drywall Screw
Drywall screw with coarse thread and bugle head / Drywall Screws with Fine Thread
Dry wall nail is a kind of nail, the biggest characteristic in appearance is horn head shape, divided into double fine tooth dry wall screw and single thick tooth dry wall screw, the biggest difference between the two is that the thread of the former is double thread.Drywall screw series is one of the most important fastener products. The product is mainly used for the installation of various gypsum board, light partition wall and ceiling ceiling series
Phosphating dry-wall screw is the most basic product line, and blue and white zinc dry-wall screw is a supplement, the scope of application and purchase price of the two are basically the same. Slightly different is that black phosphating has a certain lubricity, attack speed (into the speed of the specified thickness of the steel plate, is a quality assessment index) slightly better; Blue and white zinc in the rust effect is a little better, and the color of the product is shallow, not easy to color after coating decoration.
There is almost no difference between blue and white zinc and yellow zinc in rust resistance, only the difference in use habits or user preferences.

Galvanized connector pin R splitpin N/split Pin/ R Pin/safety Pin,Pin Matching Cotter Pin GB882 GB91,Hairpin GB91 Pin
Cotter pin is a kind of mechanical parts, in order to avoid damage to the hole wall, grease can be added to the pin hole, the production of this part needs to use high quality steel, good elastic rigid materials.Used to prevent loose thread connection. After the nut is tightened, insert the cotter pin into the nut slot and the tail hole of the bolt, and open the tail of the cotter pin to prevent the relative rotation of the nut and the bolt. Cotter pin is a kind of metal hardware, common name spring pin.
Toughness: each foot of the cotter pin should be able to withstand repeated bending, without fracture or crack in the bending part.
Bending method: pull open the cotter pin and clamp the foot part in the inspection mold (flattening phenomenon should not occur); Then the cotter pin is bent 90°, and a round trip is a bend. The test speed should not exceed 60 times /min. Inspection mold should be made out of a semicircular slot, its diameter is the nominal specification of the cotter pin. The jaws should have rounded corners r=0.5mm.
Eye circles should be rounded as much as possible.
The cross section of the cotter pin should be round, but allow the cotter pin bipedal plane and circumferential intersection there is a radius.
The gap between two cotter pins and the wrong movement of two legs should not be greater than the nominal specification of cotter pins.
Opening pin allows to make an opening, the included Angle of the plane inside its bipedal should accord with specifications.
Surface defects: there shall be no burr, irregular or harmful defects on the surface of split pins
