Key Features
Overview
The DeWalt DWMT86045OSP Mechanics 6 Point 1/4 in Drive Deep Socket 5/16 in is a SAE deep socket built for turning 5/16 inch fasteners with a 1/4 inch drive ratchet. extension. or other matching drive tool. This is a deep socket designed for fastening and service work where extra reach matters. Model Number: DWMT86045OSP.
For anyone working on small fasteners in tight mechanical spaces. the deep profile is the real reason to buy this socket. It gives you more over longer bolts and exposed threads than a shallow socket. which makes it a better fit for automotive work. equipment repair. and general shop tasks where hardware does not sit flush.
The 6-point opening is the right call when you want solid contact on hex fasteners. It is built to fit 5/16 inch SAE hardware. and the 1/4 inch drive size keeps it in the range of compact ratchets and low-profile setups that are common for lighter-duty service and assembly work.
DeWalt uses chrome vanadium steel here. which is the spec that actually matters for long-term durability. In plain terms. that means better strength in a hand-tool socket that is going to see repeated use. frequent tool-box movement. and the occasional less-than-gentle treatment on the job.
Another practical detail is the knurled beauty Simple Goods. That is not just there for looks. It helps cut down on slipping when you’re grabbing the socket with oily fingers or changing sizes quickly at the bench. under a hood. or during machine maintenance.
This is a straightforward single-socket buy for mechanics. maintenance techs. DIY users. and anyone filling gaps in a socket set instead of buying a whole kit again. If you need a dedicated 5/16 inch deep socket for a 1/4 inch drive setup. this is the kind of piece that earns its place because it handles a common size cleanly and does not waste space with extras you do not need.
Reach Longer Fasteners Cleanly
This deep socket is the right choice when standard socket depth is the problem. It gives you added reach for nuts sitting farther down on a stud. so you can stay with a compact 1/4 inch drive setup instead of switching tools.
- 5/16 inch SAE socket size for common small fasteners
