Feature
●Aluminium alloy material: made of high-strength aluminium alloy, the hardness is higher than steel, CNC lathe processing with fine workmanship, laser laser in combination with a variety of processes for producing bicycle sprocket bolts
●Anode colour – the anode is dyed to prevent oxidation, and the surface is anodised to make the colour bright and corrosion resistant. At the same time, the overall smoothness of the screw is reinforced to make the colour more dazzling and beautiful
●Product size: 6.4 mm screws are double chainring screws, 4.9 mm screws are individual chainring screws, please distinguish the size you need before you order so you get the right product
●Quality guarantee – if for any reason you are not completely satisfied with the purchase you make. Do not hesitate to send us an email, we will do our best to provide you with the right service as soon as possible. Or you just need to return the product for a full refund.

Description
Product details:
7075 Aluminum Alloy Chainring Bolts:
Explanation: Zinc is the main alloy element in 7075. The addition of magnesium to an alloy with 3%-7.5% zinc can form MgZn2 with a significant reinforcing effect, making the heat treatment effect of the alloy much better than that of binary aluminum-zinc alloys. An increase in the zinc and magnesium content in the alloy further improves the tensile strength, but resistance to stress corrosion and chipping corrosion decreases. After heat treatment, very high strength properties can be achieved.
Material 7075 is generally mixed with a small amount of copper, chromium and other alloys. Under the series, the aluminium alloy 7075-T651 is the top class. It is known as the best product of aluminium alloy. It has high strength and is far better than any other mild steel. This alloy also has good mechanical properties and an anodic response. Representative applications include aerospace, mold processing, mechanical equipment, tools and fixtures, especially for the production of aircraft structures and other high-stress structures that require high strength and strong corrosion resistance.
Bike Chainring Bolts with Fixed Wrench: Material: Tool Steel + Heat Treatment Use: Chainring bolts fixed wrench used to fix chainring bolts from one side, and with the Allen wrench to remove chainring bolts from the other side
