DIN 912 Stainless Steel Machine Allen Hex Socket Head Cap Bolts 
 
 
1.Product Description
 
Socket Head Cap Screw, Material 18-8 Stainless Steel, Plain, Drive Type Hex Socket and Thread Direction Right Hand; Varies by Head Type, Thread Dia., Thread Size and Length under Head Hex socket head cap screw, also known as the Allen bolt or allen head screw. Its head is hex socket head, and cylinder head also. Similar to the countersunk head screw, the head buried into the parts, which have the greater strength of the connection, using the proper size Allen wrench assembly and disassembly. The material are normally Alloy Steel, Stainless Steel and Carbon Steel.Socket head cap screws are ideal for precision work with close tolerances and applications whcih need a well tooled appearance. Socket head cap screws supply high tensile strength than equivalent hex head caps screws, meanwhile requiring less surface area to countersunk head screws.
Hexagon Socket Head Cap Screws
1) the six corners of the mouth of the opening of the mouth to allow the circle or sink holes
2) at the end of d<=M4 for rolling end chamfering
3) the length of the incomplete thread U<=2P
4) the top edge side of the head may be rounded or chamfered, optionally by the manufacturer
5) the bottom edge may be rounded or chamfered to Dw, but there is no burr
Six) the 6 solution bolt standard: GB/T2672, GB/T2673, GB/T2674, GB/T6190 and GB/T6191

3.Application
 
Socket head cap screws are used for applications with limited space. They have cylindrical head and internal wrenching features (mostly hexagon socket) that allow them to be used in locations where externally wrenched fasteners aren't desirable. They are used for critical vehicle applications, machine tools, tools and dies, earth moving and mining machinery, and a wide range of engineering applications. The most important reasons for the increasing use of socket head cap screws in industry are safety, reliability and economy. In this article information is given on 1936 and 1960-Series socket head cap screws, advantages of socket head cap screws, product and dimensions standards, advantages of Unbrako socket head cap screws, information on metric socket head cap screws made by Unbrako as per ANSI standard and countersunk head screws with hexagon socket.
