ZhongYue rail screw spikes railway fastener 4.6, 5.6,8.8,10.9 grade
1. Introduce:
A screw spike, rail screw (or lag bolt) is a large (~6 in or 152 mm
length, slightly under 1 in or 25 mm) metal screw used to fix a tie
plate or fasten rail. Screw spikes are fixed into a hole bored in
the sleeper. The railway screw spike has a higher cost to
manufacture than the rail spike but has the advantage of greater
fixing power; approximately twice that of a rail spike, and can be
used in combination with spring washers.
